.... The structure of the tube changes to suit it to different purposes. For example, the esophagus has very strong walls that are used for swallowing, while the small intestine is lined with villi that absorbs digested food into the body. also contains other organs that help you break up food like you teeth, your tongue, liver and your pancreas. The Esophagus is your tube that your food goes down into the stomach. If we didn't have an esophagus we probley wouldn't be alive. Your stomach is your main organ because it is the thing that makes your food into smaller units and you would die if you didn't have a stomach. Enzyme is a kind of protein that speeds up chemical reactions ....

.... were graphed showing the psychological and pharmacological effects of alcohol on human aggression, the effects of experimental aggression manipulations on intoxicated and sober patients and the consumption rate of selected beverages in the U.S. According to Buss (1961), there is direct physical aggression, physical-indirect aggression, verbal-direct and verbal indirect aggression. Graphs showed the results of the experiments. They show alcohol does cause aggression. Larger efforts might be obtained if a higher alcohol dose was given. Alcohol influences other social risk taking, moral judgement, sexual interest and nonsocial behaviors (Steele 1985). References: Adle ....

.... the human body and mind. The belief that mental abilities decline with age is a well documented phenomena. The effect of normal ageing on the ability to remember is the topic of this essay. However, it is important to note that more extreme dibilities associated with old age that affect memory (such as Alzheimer’s disease) do have similarities with the effects of normal ageing - Nebes (1992) stated that there is ‘relatively little evidence for qualitative differences between Alzheimer’s disease and normal ageing’. Examples of such similarities between the effects of normal ageing and other experimental and clinical conditions shall be discussed at relevant points dur ....

.... actions. Kuwait was a mess, but it seemed as though the allies had done their job. There was also another reason to celebrate. The allies only lost 149 troops to Iraq's thousands and thousands. On April 6, it was officially over after Iraq agreed to a permanent cease-fire. Allied troops started heading home, including Mark. There were tears and laughs along with parades and other festivities to celebrate the war's end when troops returned home to their loving countries. As for Mark, he had done his job, he defeated the enemy and kept himself alive. His own personal joy and relief overwhelmed him to the extent of asking his girlfriend for her hand in marriage. ....

.... not a viable option for the Oregon man since he is separated by such a vast geographic distance from the organ. Scientists and doctors are currently only able to keep a donor heart viable for four hours before the tissues become irreversibly damaged. Because of this preservation restriction, the donor heart is ultimately given to someone whose tissues do not match up as well, so there is a greatly increased chance for rejection of the organ by the recipient. As far as the man in Oregon goes, he will probably not receive a donor heart before his own expires. Currently, when a heart is being prepared for transplantation, it is simply submerged in an isotonic saline ....

.... Seaports made transportation for the disease swift and easy. There were reports of ships endlessly at sea with the whole crew on board deceased. When plague repeatedly returned to areas, families had no chance of reproduction. Even with better shelter and better food on the table, the family tree had no chance of maturing.2 Birth and death rates were hideously altered. Labor, taxes and industrial shrinkage soon saw the effects of plague. England's cloth trade suffered, yet never diminished. Industrial shrinkage was a great cause in the fall of the economy. With the unfortunate dying by the dozens, some were left wandering if this was a sign of the end of the wor ....

.... clinic. Only forty percents of these visits are urgent and seventeen percents are life threatening. The reason for the increase in emergency room visits are because of an estimated forty-one billion Americans who does not have health insurance coverage and the senior citizen who is growing to use the emergency room. The psyche patient and homeless patients choose the emergency room over going to a walk-in clinic or doctor’s office because it’s more convenient for them, they rather not put up in the waiting room for hours, and for the homeless patients, the know that their chances of getting a real bed is higher if they come in the emergency room. Eighty-nine percen ....

.... Doctors are now having to dish out larger sums of money in order to insure themselves adequately. Insurance companies have caught on as well, raising the price of malpractice insurance on most doctors. For instance, a doctor who would have had to pay Rs. 125 annually now has to pay up to Rs. 1500. These costs will only be passed along to the patients in the long run, and the condition is only going to worsen. Take for example the United States, where surgeons annually pay an average of $75,000 on insurance premiums. On top of these premiums, doctors who practice very defensively add as much as $21 billion US to the health care bill every year. Twenty percent of the t ....
