Fetal Development - 1,355 words
Fetal development starts with the process of fertilization. It starts when the female ovulates producing an egg. This egg then travels into the fallopian tube where it waits to be fertilized. Once sperm enter the body they must travel up the uterus until they make their way up to the egg. Once at the egg the sperm try to get in. They sperm wiggle their tails until they make it in. Once it makes it in the egg will not any other sperm in. The sperm that made it then drops its tail. After about twenty hours inside the egg the sperm finds the nucleus of the egg and fuses with it. Now the egg has all the genetic material that it needs to make a new human being. It nows begins to move down into th ...

Legalizing Marijuanna - 480 words
The purpose of this paper is to discuss marijuana and compare both sides of the issue of legalizing marijuana. We have two opposite opinions fighting each other, those who are pro marijuana and those who are anti-marijuana. These two sides have been fighting on this issue for years. Pro marijuana legalization groups such as the Physician's Association for AIDS Care argue that marijuana should be legalized in order to treat terminally ill patients. Among them are AIDS victims who find that marijuana stimulates their appetites so they can fight off dangerous illnesses. Glaucoma sufferers who have used marijuana said it has prevented them from going blind, and for cancer patients it has helped ...

Asbestoswhats This Stuff - 1,330 words
Six months ago, my husband and I purchased a small piece of property in Manhattan, Kansas to start our own computer repair business. The property was in desperate need of remodeling, but we needed to keep expenses to a minimium in order to make any profit. We had two other employees besides ourselves at this time, but as business started to pick up, we had to hire five more technicians to keep up with all the orders that were coming in. Our space was getting limited and then we were left with the decision that it was now time to get ready to remodel the building. We hired our own staff to help with the remodeling, at their request for the overtime and their experience with this type of work. ...

Who Says You Cant Compare Apples And Oranges - 581 words
It has been said that one can not compare apples and oranges. I believe differently. Apples and oranges are both delicious, edible fruits that germinate on trees and are the size of baseballs. Apples are grown in the northern parts of the United States while; oranges are grown in the southern parts. Both make a sweet, vitamin-rich juice and contain seeds. Apples are truly special fruits. Striated, thin reddish-green skin surrounds and protects the moist life inside. The layer underneath contains the white, nutrient-rich, soft tissue and tender juicy sweetness. To devour an apple, simply bite into the flesh, and eat the whole thing, skin and all. Most people avoid the core, which contains the ...

Canceris There An Effective Treatment - 1,243 words
... tumors that are too big to be surgically removed and to help destroy any cancer cells that may remain after surgery. Chemotherapy is 77% effective in killing small cases of cancer (United States Cancer Patient Survival). If a cancer tumor can be located to a specific region, surgery is used to remove the tissue the cancer has infected. Surgery is usually recommended for patients who have small cancer cells scattered throughout the body, and patients who have a single organ that is infected with the cancer. One of the main problems with surgery is that not all of the cancer may be removed. Some cancer cells are extremely small and may be overlooked during operation. Surgery is 69% effecti ...

Aids - 1,384 words
Aids by sean ross You can get tested for HIV in a number of locations -- including public clinics, AIDS organizations, physicians' offices, and hospitals. Many locations give the test for free. You can choose between anonymous tests, in which you do not give your name to the HealthCare provider, or confidential tests, in which you do give your name. Test sites should provide trained counselors who can offer you support and guidance, no matter what the test result.(Balch-97) An HIV test looks for the antibodies your immune system creates in response to the virus. These antibodies may not appear in your blood until three to six months after HIV infection. Therefore, a negative test for HIV doe ...

... ions. Preparations with a sun protection factor (SPF) of at least 15 and which block both UVA and UVB rays are recommended. SLE is typically a disease which shows a fluctuating course characterized by long periods of relative inactivity (remission) punctuated by unpredictable flares of inflammation involving one or more organ systems (exacerbation). Fortunately for a majority of SLE patients, the symptoms are so mild as to require little or no specific treatment. The choice of therapy will therefore depend both on the nature as well as the severity of the symptoms. The initial treatment of minor joint aches and pains may often consist of simple anti-arthritic medications sometimes known ...

Viral Infections - 849 words
It all started with a little tickling in my throat. I forged ahead, knowing all too well what that feeling meant, I was getting sick. I convinced myself to just not think about it and it would just go away. This whole time there was an army of alien species amassing in my bloodstream and older cells. They are horrifyingly ugly, like something straight out of H. R. Geigers imagination. They writhe and twitch while they are on the hunt for one of your precious body cells. One can almost imagine them squealing to one another "Thats the one fellas, that is the cell we turn into Fort Viri!!". Then they attack, attaching their bodies to the cells only defense, its outer wall. The cunning viri know ...

A Journey With Breast Cancer - 1,926 words
... important consideration is the stage of the disease. The stage is based on the size of the tumor and whether the cancer has spread. The following is a brief description of the stages of breast cancer and the treatments often used at each stage according to (Dollinger, Rosenbaum and Cable, 1991): Stage 0 is sometimes called noninvasive carcinoma or carcinoma in situ. Lobular carcinoma in situ, or LCIS, refers to abnormal cells in the lining of the lobule These abnormal cells seldom become invasive cancer. They mean there is an increased risk for developing breast cancer. The risk is increased for both breasts. Some women with LCIS may choose to take a medication called tamoxifen in an at ...

Multiple Causation Theory Of Leukemia - 1,920 words
Leukemia is a malignant disease of the bone marrow and blood. It is characterized by the uncontrolled growth of blood cells. The term leukemia has a Latin derivation. Leuko means white and heme is blood. Therefore the word leukemia literally means white blood. The common types of leukemia are divided into four major categories: myelogenous and lymphocytic, which can then be divided into acute or chronic. Thus, the four major types of leukemia are acute or chronic myelogenous leukemia and acute or chronic lymphocytic leukemia. Acute leukemia involves the most primitive types of leukemia cells. It is a rapidly progressing disease that results in the accumulation of immature cells in the marrow ...

Marijuna - 1,316 words
Marijuana, the crude drug made from the leaves and flowering tops of the cannabis sativa plant, contains hundreds of active chemicals. Of the 421 chemicals identified in the plant, 70 are cannabinoids (chemicals found only in the marijuana plant and nowhere else in nature). Cannabinoids are stored in the fat parts of cell membranes for long periods of time and interfere with normal cell functioning. Since the 70 annabinoids are fat-soluble, they build up or accumulate in body tissue. Three to seven days after using marijuana, a 50 percent level of biochemical activity will remain in the cells. It takes the body 20 to 30 days to metabolize or wash out the chemicals from the marijuana. Some cl ...

The most basic function of the circulatory system is to move the blood. The organ that provides the force to push the blood through the vessels is the heart. The mammalian heart is composed of four chambers to which large blood vessels are connected. The walls of these chambers are made of cardiac muscle tissue. It is the contraction of these muscular walls in a synchronized manner that moves the blood through this pump and i ...

Ulcers - 1,963 words
Millions of people around the world suffer from ulcers. An ulcer is a sore or hole in the lining of the stomach or duodenum (the first part of the small intestine). People of any age can get an ulcer and women are affected just as often as men. With stomach ulcers, H. pylori infection is found in 60 to 80 percent of the cases. Again, it is still uncertain how the infection acts to cause the ulcer. It probably weakens the protective mucous layer of the stomach. This allows acid to seep in and injure the underlying stomach cells. However, there is still a great deal of research to be done to unravel this relationship. In times past, physicians were taught "no acid, no ulcer." The medical profe ...

Lupus - 1,168 words
Lupus is a chronic, autoimmune disease which causes inflammation of various parts of the body, especially the skin, joints, blood and kidneys. The body's immune system normally makes proteins called antibodies to protect the body against viruses, bacteria and other foreign materials. These foreign materials are called ANTIGENS. In an autoimmune disorder such as Lupus, the immune system loses its ability to tell the difference between foreign substances (antigens) and its own cells and tissues. The immune system then makes antibodies directed against "self." These antibodies, called "auto-antibodies" react with the "self" antigens to form immune complexes. The immune complexes build up in the ...
