... body is supplied by series of blood vessels. Portal circulation in addition to the pulmonary and systematic circulations described above, a subsidery to the venous system exists, known as portal circulation. A certain amount of blood from the intestine is collected into the portal vein and carried to the liver. Coronary circulation is the means by which the heart tissues themselves are supplied with nutrients and oxygen and are freed of wastes. Just beyond the semiluna valves, two coronary arteries branch from the aorta. Heart action consists of systole and relaxation of the muscular walls of the atria and ventricles. During the period of relaxation, the bl ...

... virtually any of the body's cell (Dorfman, 60). Mid-facial abnormalities are a part of the child for life. Some of these common abnormalities are a broad nasal bridge, poorly developed filtrum, thin upper limit, flattening of the axillary area, and a short upturned or beak-like nose. Some of the more serious effects that can be more dangerous are a poor dental alignment, optic nerve defects, and arterial septal defect (Welkselman, 297). Welkselman thinks that affected infants frequently are measured at birth to be below the tenth percentile for their age in length, weight, and head size. These children never catch up to their peers and they remain in the ...

... cost and cash flow. One technique that seeks to discover true cost levels is a commercially used management accounting system, activity-based costing. Activities that drive cost levels are identified and then analyzed in terms of their value to the production of the end product. For health services the end product would be the aggregation of applied procedures, tests and therapies related to a particular patient treatment. Accounting systems categorize expenditures in terms of labor, materiel and capital, allocating pools of common expenses and overhead that can't be directly traced to a specific product or service. The impreciseness of most allocation te ...

... the disease. Most people believe that anorexia is mainly a young females' disease. This is not necessarily true. In fact, studies within the past few years show that male anorexia is about as widespread as in females. In actuality, 80 percent of the people diagnosed with anorexia over the age of 45 are males(Heywood, 1996). Other misconceptions are that anorexia is only common with younger people and that anorexia is not a real disease at all, just a staple of obsessive teenage girls. Another widespread misconception about the disease of anorexia is that it is a new disease. Actually, doctors say that anorexia has its roots centuries ago. Through different ...

He calls ADD a neurological disorder that affects the motivational system (42, 20). Another theory of what causes ADD is the low amount of glucose metabolism in the brain. ADD affects two important parts of the brain that are connected with the ability to pay attention and the ability to regulate motor activity (Phelan 46). Many people believe that bad parenting, physical brain damage, diet, and allergies cause ADD. Thomas Phelan argues that these things indeed do not cause ADD. People also believe that ADD can be hereditary. Better than one th ...

... this technique for the mental aspect of fundamental skills. Psychologists recommend that athletes mentally practice their events on the eve of competition. When it comes to sports, the winning edge throughout the world of sports may have less to do with strength and talent, and more to do with, what sports psychologists call it, mental toughness. Sports psychologists James Loehr, calls "mental toughness," the ability to handle and even enjoy the psychological pressure of a competitive situation. (Harry Hurt, 1996, p.12) Many of today's best athletes seek help from sports psychologists, in order to help them with their overall game. Negative thoughts and psycho ...

... why should they go through the suffering when they will die anyway. Physician assisted suicide should be legal in all states because it ends the suffering of many ill people. People have a right to die if they choose to. The only problem is that some states have decided to not allow physician assisted suicide. For example, people like Dr. Kevorkian has been under much scrutiny for assisting in deaths. I don’t necessarily agree with his bedside manor and his “icy okey-doke” (Goodman, 495) But when somebody decides to take his own life, it is up to the individual to do so. Another problem is the moral issue. Is assisted suicide moral or immoral? If a person is termi ...

... side-effects. Various studies have claimed that cannabis destroys brain cells. However, several other studies found no structural or neurochemical atrophy in the brain at all. Furthermore, it should be noted that Heath's work was sharply criticized for avoiding safeguards of bias and reporting "changes" that occur normally in the mammalian brain. Wu et al. found a correlation between cannabis use and low sperm counts in human males. This is misleading because a decrease in sperm count has not been shown to have a negative effect on fertility and because the sperm count returns to normal after cannabis use has stopped.. Another claim made was that cannabis cau ...

... involved relatively short-term observations. With the recent increase in participation in general fitness activities, and with such participation being encouraged by the medical community as a public health intervention to promote healthy lifestyles, it often is not realized there is little or no dependable data available to assess the risks involved in participation in physical activities. Much effort is being expended in defining the benefits of exercise, but little is being done to define risk levels. Such information is needed in order to make informed decisions as to the value of participating in a particular activity, and to provide clues as to how ...

... 50 percent or more infections result from homosexual contacts. Other infections like syphilis, herpes, and HIV infection may be passed on to the fetus or during childbirth. The fetus or baby can suffer from the disease and can die from it. The helping of STDs has three parts: treatment, counseling, and following up. Sometimes treatment is given in a single dose but in sometimes you have to take it more than once. A person can still be infected even if the symptoms go away. That is why a follow-up visit is important. To avoid spreading the infection the person should not have sex until the doctor says that it is cured. It can take up to fourteen days. This stops th ...
