Streetcar Named Desire as a Play and as a Film Essay
Streetcar Named Desire as a Play and as a Film - Essay Example Society was still immersed in a political climate not conducive to equal rights without regard to race or gender let alone sexual orientation. In the original version of the piece, seen as a play, the audience finds out that Blancheââ¬â¢s husband killed himself shortly after she found him in bed with another man. The version which the audience is given in the film is much more suggestive with an expectation for its audience to read between the lines rather than a forward approach to the information which is given in the play. With regard to the issue of Blancheââ¬â¢s rape by Stanley, the play is sure to embrace this incident as it is crucial to the ââ¬Ëtake-home messageââ¬â¢ intended originally by Williams. The movie seems to understand this ironically moral inclusion but not without a tradeoff which came in the form of the punishment of Stanley for his actions which is really not part of the ambiance of the play. The issue of Blancheââ¬â¢s rape and her husbandââ¬â¢s homosexuality and suicide are the heavier topics demanding a presentation appropriate for their display during that time period, but are not the only morals to the story, so to speak. There are other themes which exist both in the play and in the movie version of Williamsââ¬â¢ work. In looking at the movie first, the beginning is the first of many small deviations. The movieââ¬â¢s audience finds Blanche who seemingly emerges from the steam of the train, in an almost ethereal or heavenly manner. This is a contrast because though Blanche is introduced to the audience in this light, she is taken from a place of presumed innocence through the film, only to be displayed as anything but that. The play does not make the same attempt at disillusioning the audience that the film makes at the pieceââ¬â¢s beginning, but beyond this point, the play and the movie are overall quite similar with little variations.

Environmental Science Essay Example | Topics and Well Written Essays - 1500 words
Environmental Science - Essay Example The pollution of the environment is caused by residential, commercial, and industrial wastes. These include Carbon dioxide (COà 2)), Carbon monoxide (CO), Nitrogen, and Chlorofluorocarbons (CFCââ¬â¢s) (ENERGY.GOV, 2014). The release of such compounds into the environment leads to environmental degradation. Therefore, it is prudent for human beings to take necessary steps in preventing any further damage to the environment and mitigate on the damages that have already occurred. This responsibility is a concern of the international community, respective governments, and every individual. The individuals can work hard to care for the environment by participating in environmental conservation measures. It is important for individuals to take care of the environment because it is where they live. Polluted air means that there would be an increase in respiratory diseases. Furthermore, polluted soil, full of chemicals and fertilizers, will result into crops with high levels of toxic su bstances and pollute the water bodies when these fertilizers are washed into streams and rivers. This paper explores three goals and action plans, which an individual can use to become more aware of environmental issues and human impact on the environment. The production of electricity often involves a lot of emission of gasses, which cause considerable damage to the environment. Therefore, an individual should bear this in mind when operating electrical appliances. This can involve a slight change in their habits or using more energy efficient appliances. For example, change of habits include: Using cold water to wash laundry and hanging them out to dry instead of using the dryer. This habit will ensure that when doing laundry, less electric energy is consumed, and the one utilizes the abundant natural energy of the sun to dry the clothes Installing energy efficient bulbs, which save more energy and are longer lasting as compared to incandescent light

Development from Birth - 19 Years Essay Example for Free
Development from Birth 19 Years Essay The aspects of development are defined as Physical, Social Emotional, Language and Intellectual. There are different stages of development for each category, 0-3 years, 3-7 years, 7-12 years and 12-19 years. All children will follow the same pattern of development but at different rates and will reach their milestones at different times. Physical During the 0-3 year period a childââ¬â¢s physical development will see them start to move and react to memorable sounds and voices. They recognise people, reach for brightly coloured or noisy items. Their ability to move begins with rolling over, moves to crawling, shuffling and finally the ability to walk. Fine motor skills will also increase, from being able to hold and shake interesting objects to using crayons to scribble and make marks. They will use body language to communicate, such as shaking the head to indicate ââ¬ËNOââ¬â¢. As they move into years 3-7 their skills become more refined, they will be able to walk up and down stairs, catch a ball, use paints. Then they will learn to pedal a bike start to draw basic pictures of people or houses. Movement continues to improve and they become confident at climbing and jumping and their fine motor skills allow them to write more clearly, sew and manage shoe laces. By ages 7-12 years children are generally able to hit a ball and participate in team sports although their ability may not meet their own expectations at first. During adolescence physical development becomes more about appearance and the process of puberty. Whilst girls begin this process earlier than boys all children will develop as individuals. This can be a very difficult time for teenagers, with insecurities about they way they look and how they compare to their peers. Some will suffer anxiety at some point and worry about being a late or early developer. Social and Emotional Social and emotional development begins by showing affection and becoming attached to parents or carers and becoming what we usually call ââ¬Ëclingyââ¬â¢. Young children may become distressed when a parent leaves the room or is not in sight. Slightly older children may demand attention and use tantrums to get their own way. They will generally be easily distracted from unwanted behaviour. By age 2-3 years children enjoy playing with older people who provide them with attention and begin to enjoy time with children their own age. Over the next few years the child becomes more independent and coopertative and likes to help. They develop social skills and play with others is more comfortable as they begin to consider the feelings of others and make friends, although resolving disputes can still be an issue. Rules and routine are required to help the child feel secure and safe. In later years the child becomes less dependant on their parents and moves closer to their peers. They develop a sense of right and wrong by may still adult intervention to settle arguments. They become aware of their gender and normally prefer the company of their own sex. Their behaviour differs with their emotions depending upon circumstance. In the final stages of development puberty creates feelings of self-consciousness and insecurity about body image. Behaviour is very unsettled as they sway between the feelings of being a child and wanting to be an adult. Friendships become stronger and adolescents depend less on the parents. They are much more aware of the opposite sex and need to fit in social with their peer group. People of this age begin to think about their social environment and may start to form strong opinions about community, politics and religion. Language In the early stages of development language is more about making sounds to show feelings. Babies watch others to learn facial movements to help them to begin making their own sounds and will turn towards sound they hear. From making sounds, words develop and gradually increase in number. They begin to understand key words spoken to them and will repeat back what they hear building from single words, to phrases and then sentences. Childrenââ¬â¢s ability to understand develops faster than the ability to speak and this can cause frustration with not being able to express themselves. During the 3-7 year period children begin to question things more intently, use more accurate grammar and their vocabulary increases dramatically. Reading skills start to develop, first recognising a few frequently seen words and understanding stories and books. During the Key Stage 1 years learning and recognising letters and the sounds they make develops into reading and later into writing. The next stages of language development involves the vocabulary increasing further and learning to spell more difficult words. Adult interaction is important to help children learn fluency and progress towards telling more complicated stories and the correct use of grammar and tenses. During adolescence language becomes more mature and logical thinking begins to develop. They can be sarcastic and begin to experiment with humour or may wish to publicly demonstrate their new found skills. Intellectual Early intellectual development involves copying others through play and testing different styles of behaviour. Young children also begin to recognise that all people are separate from themselves. Next comes the ability to understand instructions and recognise things that are similar, for example, shapes and colours. Between 5-7 years children start to become aware of their environment and understand what is means when things are different or the same. Next a child will develop their own interests and reading becomes a skill used for entertainment. Finally the mind matures and young people learn responsibility for their own thoughts and actions. They begin to think about their future lives and things they might like to do like, jobs, marriage and children. The ability to make connections between pieces of information and the world around them also matures. The speed of development at this stage very much depends upon the amount of guidance received. The more guidance a person gets the quicker they are able to reflect upon how things relate to in practice to their lives. An individuals personal identity is formed from the things they learn at this stage which should be more moral and cultural. Adolescents begin to take more responsibility away from their parents with regard to managing their finances, employment and their personal relationships and becomes complete during adulthood.

The Peloponnesian War :: essays research papers fc
The Peloponnesian War Is war inevitable? It appears that the answer to this question is yes. However, war is unpredictable and must be studied based on individual circumstances, actions taken, and reactions. States disagree with each other on many subjects and conflicts arise often. To answer this question, we must first examine the causes of a conflict, evaluate the outcome and determine any alternatives that may exist. Then we can analyze some alternative theoretical outcomes compared to the actual conclusions. The Peloponnesian War provides an excellent example to be evaluated. The following gives a brief history of the war, causes of the war, and the importance of its study. In the case of the Peloponnesian War, we have two equal but different powers in control of Greece and the surrounding area. Athens and Sparta as allies gained independence from the Persians in 480 BC. Athens with a democratic rule expanded by using the surrounding waterways for trade and developing a great navy. Sparta with an oligarchic rule settled in by developing a thriving agriculture community and a land based army. Civil war occurs in Epidamnus with two sides, democratic and oligarchic. The democrats requested assistance from Athens. If Athens chooses to get involved, she breaks the truce with Sparta. If she does not, the balance of power leans towards Sparta and her allies. Sparta already feared Athensââ¬â¢ growing power. Therefore, Sparta needed to check Athensââ¬â¢ control of the region. The need to keep a balance of power is the main reason of the Peloponnesian War. Thucydides attains that Spartaââ¬â¢s fear of Athenian rule provided an unavoidable path to war. Athens controlled about half of the city-states; dominated much of the trade; and maintained a strong navy. Sparta kept a strong army and retained equal allies but was primarily an agriculture state. Athensââ¬â¢ ability to maneuver on the sea provided opportunities to expand her power, and this alarmed Sparta. Since Sparta is concerned by Athensââ¬â¢ growing power, Sparta waits for a way to be able to stop the expansion. When an opportunity comes for war against Athens, Sparta is not very reluctant and could even be considered eager to enter an altercation. Pericles leadership appeared sound but may have over reached the power of Athens. Pericles convinced the Athenians that allowing allied states to become free was a sign of weakness. In addition, he convinced them that Sparta was no match and could not win a long-term war against the great Athenian navy.

Persuasive Essay on Positive Thinking Essay
Positive thinking is a skill that I believe everyone should master and use as a everyday way of life.First you need to know the law of attraction. From there you can start a new life style that can only really benefit you. The law of attraction is how positive energy attracts positive energy and negative energy attracts negative energy. There is a man named Morris Goodman I learned about in the book The Secret, by Rhonda Byrne. His story is amazing. Morris Goodman was in a plane crash march of 1981. Morris surrvived the plane crash but was left paralyzed, his spinal cord was crushed, and his diaphram was destroyed which left him unable to breath on his own. He lost the ability to do anything but blink and think*. No one thought he would be much of anything ever again because of the severity of his injuries. Morris did not believe this. He set a goal of walking out of that hospital by Christmas. All Morris did was focus on breathing, and walking, and being positive, not allowing anyone or anything distract him from his goal. He did, Morris achieved his goal. Doctors were at a loss for explanation, but Morris Goodman walked out of that hospital before Christmas. Morris Goodman is The Maracle Man. He proved that whatever you put your mind to you can do. The power of positive thinking can benefit everyone in countless ways; increase self esteem, increase confidence, and a more relaxed state of mind. Just to name a few. Ã You see the consequences of negative thinking everyday. You see it in war and violence, even on the local level. Depression and poverty are often consequences of negative thinking as well. Ã Could you imagine what the world would be like if the whole world believed they could achieve anything they dream of? Could you imagine what your life would be like if you truely believed you could achieve anything you want? If you are always thinking positive there is no room for the negative. Increase of self esteem, confidence, a more relaxed state of mind will all manifest from just that . This is a skill that I believe everyone can benefit from. * Some of this info taken from themaracleman.org run by Morris Goodman.

Deoderent Market in India Essay
Abstract Topic:- Monopoly or monopolistic competition in Deodorant brands? After seeing so many outrageous deodorant advertisements on television we were wondering whether it affects the consumer behavior and we also wanted to find out whether Axe has a monopoly over this market or not. The aim of this assignment is to compare the parent companies of five deodorant brands with the help of ratio analysis. We are going to consider the time period 2007-12. Primary data was collected through a survey which will help us determine what thinking goes behind purchasing a deo between college students and the office going crowd. To conduct the ratio analysis we used secondary data by obtaining the balance sheets of the various companies. The market share and revenues of five major brands- Axe, Adidas, Nivea, Wildstone and Park Avenue will be analyzed. Introduction Monopolistic Competition Monopolistic competition is a type of imperfect competition such that many producers sell products that are differentiated from one another as goods but not perfect substitutes (such as from branding, quality, or location). In monopolistic competition, a firm takes the prices charged by its rivals as given and ignores the impact of its own prices on the prices of other firms.[1] In a monopolistically competitive market, firms can behave like monopolies in the short run, including by using market power to generate profit. In the long run, however, other firms enter the market and the benefits of differentiation decrease with competition. There are six characteristics of monopolistic competition (MC): * Product differentiation * Many firms * Free entry and exit in the long run * Independent decision making * Market Power * Buyers and Sellers do not have perfect information (http://en.wikipedia.org/wiki/Monopolistic_competition) Economic Background The deodorant market in India is estimated at Rs 900 crore. Menââ¬â¢s deodorants dominate the category with a 70 per cent share estimated at Rs 650 crore. The segment is expected to grow 25 per cent annually to become three times its current size in the next five years. The overall deodorant market has grown by about 40 per cent a year in the past five years driven by introduction of new brands and aggressive media promotions. The market will continue to grow at 20-25 per cent thanks to low penetration and availability at low price points. Deodorant sales are seasonal ââ¬â maximum sales happen in the summer months (April to September). About 90 per cent of the market is concentrated in the mass segment (with deodorants priced between Rs 125 and Rs 175 for a 150 ml pack). With new players entering the category at popular price points, the mass segment, with brands like Axe, Adidas, Nike and Reebok, will continue to grow faster and command higher share in the deodorant market. The size of the premium and above segments, which have brands like Burberry, The Body Shop, Kenzo and Ralph Lauren, will double by value in the next five years. (http://www.business-standard.com/india/news/kit-the-men%5Cs-deodorant-market-in-india/443714) Method We will be using the financial tools of various ratios to determine which company has been more successful in this market. Survey The survey was conducted on 200 males in the college and office going crowd the results were as follows. 1. Which Deodorant do you use? Analysis As we can see from the above graph that Axe has a majority amongst the people surveyed while the others are below 10%. This gives us a picture of the domination of Axe in this market and same is the case when market share all over India is observed. 2. Reason for buying the particular brand. From the above graph we find that the decision of people in the age group of 15-25 behind buying a particular deodorant is not its fragrance but its price followed by easy availability and advertising. This shows us that main factor which affects a consumerââ¬â¢s decision, in this age group is the price of the product followed by other factors regarding quality, availability etc. This was the result obtained from the office crowd which gave an entirely different reason. The consumers decision in this age group is affected by the brand as people become brand conscious and are more bothered about which brand they use rather than its use. After the brand value the price affects their decisions. Hence from both these results we see that consumer behaviour varies on the different age groups and changes as a consumer grows older. Findings: Name: Mahikaansh Reddy Brand: AXE (Hindustan Unilever) AXE was launched in France in 1983 by Unilever. It was inspired by another of Unileverââ¬â¢s brands, Impulse. Unilever were keen to capitalize on AXEââ¬â¢s French success and the rest of Europe from 1985 onwards, later introducing the other products in the range. Unilever were unable to use the name AXE in the United Kingdom and Ireland due to trademark problems so it was launched as Lynx. The European launch of the deodorant was followed by success in Latin America and moderate impact in Asia and Africa. In the new millennium, the brand has launched with great success in the United States and Canada. The company has also consolidated its deodorant portfolio by migrating other overlapping male deodorants into the Lynx brand such as South Africaââ¬â¢s Ego brand. In January 2012, Unilever launched its first Lynx product for women in the United Kingdom as part of a global expansion of the previously menââ¬â¢s-only brand. The AXE deodorant was popular in India in the Grey market (duty paid shops). Impressed by the volume of AXE sold there, AXE deodorant was launched in India in 1999. The brand launch was very quiet and had the strategy of ââ¬ËHigh Price, Low Promotionââ¬â¢. At that time, the deodorant market was a nascent one with an estimated market size of Rs 72 crore. HLL, at that time, had the brands Denim and Rexona and was ruling the market. AXE was priced at a premium. In just three years flat, AXE had a market share of over 35% and HLL started phasing out Denim to concentrate more on AXE. It is known for its very controversial advertisements which actually helped in its publicity and led to a faster growth in the industry. Its target group was mainly men between the age group of 18-24 as they were seen as the easiest to convince with such advertisements. Not only does the brand use TV commercials to its advantage, but it also uses its print ads effectively. Besides print, the brand also uses outdoors for maximum impact. Hence, Axe is a classic example of the 360 degree branding effort. Therefore Axe is a perfect example of how important advertising is for a brand and how it can lead to higher revenues. Marketing Mix 1. Product: 2. Place: Available at all malls across India. Every deodorant selling shop will 99% be selling Axe. All other variants of Axe brand could be purchased from established retailers viz. BIG BAZAAR (PANTALOONS RETAIL INDIA LIMITED). 1. Promotion: Concentrates on single- segment male youth and targets young at heart. The competitive advantage of this brand is its complete monopoly over this proposition. The ââ¬Å"Axe Effectâ⬠is one of the most famous claim in the world. This so called effect is supposed to draw women in hordes to any male who has sprayed himself liberally with the Axe deodorant. The advertisements are very slick and usually display a normal male but with oodles of self-assurance as an Axe user. The females get irresistibly drawn to this male implying that Axe acts like a nasal aphrodisiac. 2. The Axe brand of deodorants is from Unilever and is primarily targeted at 15 to 25 year old males. The brand portrays normal yet cool, trendy and confident, a positioning that is aspirational to the target segment. At a more subtle level, the Axe Effect also acts on the confidence levels of the user. The very act of being associated with the brand serves to boost the ego. The success of AXE attracted lots of new brands which were trying to follow the same marketing strategy as AXE. The one notable difference though is that all these newbies use hunks as opposed to the regular guys which are a stable for the Axe advertisements. This strategy has proven very effective for the brand. It comes across as approachable and it acts like a confidante and friend to its users. They are currently distributed in more than 40 countries. Unilever started out allotting roughly 60 percent of its advertising budget to television, but it has since winnowed that down to about 30 percent, pouring more money into offbeat alternatives. Competitive analysis: Axe faces competition from new entrants such as Wildstone, Adidas, Park Avenue etc. However among all these brands AXE has a dominating share in the market because of the brand equity and brand loyalty that it has built and is leveraging the same. AXE has a wide acceptance among the youth which forms the major chunk of perfume & deodorant users. Vis-à -vis all these the AXE deodorant never forgets to promote any of its new product. AXE time and again, on launch of the new product goes for PR as well as wide advertising campaigns. 3. Target group- 18 to 24 What next? As such, I believe that AXE has the potential to spread its reach and increase its market share by expanding into the 35-50 year old demographic. In doing so, AXE will need to associate and disassociate itself with a more mature brand image and its inexpensive nature respectively, thereby attracting the average male aged 35-50 years. Hence it needs to re-focus the marketing mix towards 35-50 year old demographic, whilst retaining its keystone market, the 16-25 year olds. Conclusion Axe has a very large share in this market and has hardly got a foot wrong. It just needs to follow its tried and tested market strategies and build upon it, by doing that it can thwart the competition and maintain its kind of monopoly in the market. The only thing that could be suggested is to increase its target group so that it could expand more in the market and serve a larger base leading to higher revenues. Hence Axe just needs to follow what it was doing from before and be wary of the new competition in this segment with the help of excessive advertising and PR.

buy custom Heart and Blood Vessels essay
buy custom Heart and Blood Vessels essay 1. Complete the following scheme of blood circulation in human heart. Right atrium through the tricuspid valve to the right ventricle through the Pulmonary valve to the pulmonary trunk, to the semi lunar for oxygenation, to the pulmonary veins back into the left atrium of the heart, through the mitral valve into the left ventricle, through the left semi lunar valve into the arteries, that supplies systemic blood to the body and then deoxygenated blood goes back into the right atria via tricuspid valve, superior vena cava and inferior vena cava pulmonary artery. 2. The beating of human heart (cardiac cycle) directly reflects the electrical conduction system within the heart (ECG). Describe what happens in the cardiac cycle in the following situations: a. Immediately before P wave: Senatorial node fires causing the contraction of atria. Before this hearts resting period no electrical activity is performed and muscles relax to fill the atria with blood. b. During P wave: At the sinoatrial node the contraction of heart muscle starts. It last for 0.08 seconds. P wave slows down the process of depolarization at the end. c. Immediately after P wave: The P-R segment occurs immediately the P wave occurs. This P-R segment is time travel to reach the ventricles from SA. After this the QR complex occurs. d. During QRS wave: the depolarization wave movements is depicted through the QRS complex. It makes large upward spikes. The QRS complex shows the conduction depolarization waves synchronously. e. During the T wave: It is the last readable wave in a cycle on ECG. Hearts re-polarization is represented here. It means that ventricles have sent the blood to the body and heart goes to reset itself for the next cycle (Elaine 696). 3. Suppose a person has a heart rate of 70bpm and has a stroke volume (SV) of 70ml. A negative inotropic agent (any substance that reduces contractility of heart) reduces the SV to 50 ml. What would the new heart rate have to be to maintain the same cardiac output? Heart rate: 70bpm Stroke Volume SV: 70 ml Cardiac output = HR x SV = 70x70 =4900 ml/min SV after reduction = 50 ml Cardiac Output: heart rate x Stroke Volume = 70 x 50, 3500 ml/min or 3.5 L/min New Heart rate = Cardiac output/ Stroke Volume = 4900/50 = 98bpm 4. A 55-year-old male was admitted to the hospital with heart failure. He complains of increasing shortness of breath on exertion and needing to sleep on three pillows at night. On physical assessment, the nurse determines that his ankles and feet are very swollen. Which of these symptoms reflect left-sided heart failure and which reflect right-sided heart failure? Answer: The left sided heart failure occurs due to reduction in cardiac output of arterial blood. Other symptoms of left ventricular failure include as the hypoxia, crackles, cyanosis, fatigue, dyspnea, paroxysmal nocturnal, elevated pulmonary and capillary wedge pressure. Right side heart failure occurs due to weight gain. Dependent pitting edema is also observed in patients feet and ankles. This edema is disappeared overnight but spreads in other tissues. Other symptoms of right side heart failure include the weakness, jugular vein distension, vomiting, and nausea, elevated and central venous pressure (Barbara and Nancy 426). Use the following hint to solve the problem: -Think about the normal flow of blood within the heart - Now think, what will happen if the left side of the heart is not pumping properly. Where will the blood pool up. Now try to think about the symptoms the patients may experience due to pooled up blood. -Repeat all these steps for the right side of heart as well. 5. Becky, age 2, was born with a hole in her interventricular septum (ventricular septal defect or VSD). Considering that the blood pressure in the left ventricle is significantly higher than the blood pressure in the right ventricle, predict the effect of VSD on Beckys 10 points a. pulmonary BP: The VSD creates the greater pressure on two ventricles, it is higher in left ventricles than right ventricles. The VSD allows the oxygenated blood to flow from the left ventricle to right ventricle. In right ventricle the pressure is low and mixed blood the flows to circulate into lungs. It is not apparent in infant at the time of birth because left ventricular and right ventricular pressures are equal. As the child grows the right ventricular pressure decreases and blood shunts from left ventricular to right ventricular. Becky will suffer from the occurrence of cyanosis and biventricular heart failure. Chest wall will become prominent and resulting into increased risk of pneumonia for Becky. b. systemic blood pressure. Systemic blood pressure is disturbed due to effects of VSD in an infant like Becky. VSD is not closed in Becky so blood flows under higher pressure into arteries and arteries become thicker. Right ventricular works extra to control the high blood volume and lungs receive the extra blood pressure. Lungs are permanently damaged due to this blood pressure. Explain why? 6. Based upon the topic of blood pressure and the factors controlling blood pressure, for each of the given situations, describe the anticipated effect on blood pressure and the physiological basis (reasoning) of your response; a. A high salt diet: kidneys are the organs to control the level of salts in our body. When intake level of salt is high then kidneys cannot control the level of salt and it ends up into blood stream. Salt requires more water into blood which results into increase volume of water. This increases the volume of blood and blood pressure is also raised. It is also noted that hypertrophy is linked with excessive amount of NaCl. b. A blow on head that damages (disables) the vasomotor center: The process of vasoconstriction is controlled by the vasomotor center in brain. This process of vasoconstriction regulates the blood pressure. When this vasomotor centre is disabled them improper vasoconstriction may cause the increase in blood pressure and hypertension. c. Hypothalamic tumor resulting in excess ADH production: There are two causes behind it. Firstly, it makes the kidneys to retain more volume of water which increases the blood pressure. Secondly, it causes the blood vessels to squeeze down and causing the blood pressure to go up. Due to elevation of ADH, kidneys start to retain excessive volume of water resulting into expansion of plasma volume. This expansion in plasma volume causes the blood pressure to increase 7. Edema (swelling due to increase in interstitial fluid) is a common clinical problem. On one of your first days of introductory clinical experience, you encounter three patients who all have severe edema for different reasons. Your challenge is to explain the cause of edema. Note: In each case, try to explain the edema in terms of either an increase or decrease in one of the four pressures that cause bulk flow at capillaries (refer to slide # 76-80 of ppts.) a. First, you encounter Mrs. Taylor in medical ward awaiting a liver transplant. What is the connection between liver failure and her edema? HINT: think about role of liver in producing plasma proteins. Osmotic positional of plasma drops resulting into drop of plasma protein concentration. Capillaries absorb less fluid of interstitial. This condition of plasma protein reduction becomes the cause of edema. Liver failure also causes the decreased synthesis of plasma protein. The persons with liver failure have the impaired synthesis of albumin which causes decrease in colloidal osmotic pressure. Edema is also developed due to lack of amino acids required for the synthesis of plasma proteins (Carol 165). b. Next, you follow a resident to obstetric ward, where Mrs. So is experiencing premature labor. Which of the pressures that drive bulk flow might be altered here? HINT: What affect the expanding uterus might be having A pregnant woman may feel the labor pains prematurely before 37 week of pregnancy because cervix opens before the time due to uterine contraction. Baby born may face the health problems, but medicine, new technology and research the baby becomes healthy. These women have the cervical abnormalities. There are other factors which cause the alteration in blood volume in pregnancy. Cardiac output also affects the normal delivery. c. Finally, you are called to emergency, where Mr. Herera is in anaphylactic shock. Which of the pressures that drive bulk flow might be altered here? HINT: In anaphylactic shock, the capillaries become highly leaky. In anaphylactic shock the fluid buildup in the body tissues which results into an edema. This occurs due to high osmotic pressure in capillaries and low osmotic pressure in tissues. Blood has to reach the tissues but it diffuses back into capillaries. In anaphylactic shock blood from sides is prevented to enter the capillaries, tissues are swallowed and patient expires. The blood circulatory system has been discussed in this paper. A related numerical is also part of this paper. Buy custom Heart and Blood Vessels essay
