The blood away which carry the bright red oxygenated blood away from the heart are called arteries. The large arteries, which receive the blood directly from form the heart, branch repeatedly until every part of the body is served by one or more of them.
The blood returns from all parts of the body to the heart through veins. There are many more veins than arteries throughout the body. The veins gradually unite to form larger veins as they approach the heart.
When the blood is sent out over the body through the arteries it passes into the capillaries in which the arteries end. The capillaries are tiny hairlike blood vessels forming a network throughout the body. The tissue is so well supplied with capillaries that even a pinprick is likely yo break some of them and result in the appearance of a few drops of blood.
When an artery, vein, or capillary is broken or cut, blood flows the broken vessels. Usually the blood flow the broken blood vessels is stopped by the formation of a clot in the end of the broken vessels. Bleeding from a large artery comes in serious. The blood from a served artery is extremely serious. The blood from a served artery comes in spurts. There is a smooth flow of blood from veins.
The pumping action of the heart ceases only with death. Ay and night, year after year, it continues to work in pumping the blood throughout the body. It can rest only by pumping more slowly or less powerfully.
The heart is a hollow, pear-shaped muscular organ located just slightly to the left of the midline of the body in the chest cavity. It can be located easily by the sound of the heartbeat or the feeling of its contraction through the skin and muscle that lie over it.
At birth the heart beats about 130 times a minute, at six years it beats 100 times a minute, at ten years about 90, and at fifteen years about 85. The approximate normal heart rate among adults ranges from 65 to 80 betas per minute. During a lifetime the heart beats 2,500,000,000 times and pumps a total of nearly 15,000,000 gallons.
The impulse which causes the heart to contract develops in some nerve tissue which is called the peacemaker of the heart. An attempt to measure this impulse indicates that its energy is the equivalent of one-thousandth of a volt.
The blood from all parts of the body empties into the heart through large veins. Then it is sent through the lungs, where it acquires a new supply of oxygen. The blood the returns to the heart from the lungs. When the heart muscle contracts, the blood is forced out the heart, then goes by away of the large arteries and capillaries to the farthest extremes of the body.
The heart moves a total of five hundred gallons of blood a day. Since there are about six quarts of blood in the whole body, the heart moves the same fluid, slightly modified chemically as it travels about, over and over again
Clozapine Side Effects Management Clozapine (sold as Clozaril, Azaleptin, Leponex, Fazaclo, Froidir; Denzapine, Zaponex in the UK; Klozapol in Poland, Clopine in Australia and New Zealand) is an antipsychotic medication used in the treatment of schizophrenia, and is also used off-label in the treatment of bipolar disorder. Wyatt. R and Chew. R (2005) tells us there are three pharmaceutical companies that market this drug at present: Novartis Pharmaceuticals (manufacturer), Mylan Laboratories and Ivax Pharmaceuticals (market generic clozapine). The first of the atypical antipsychotics to be developed, it was first introduced in Europe in 1971, but was voluntarily withdrawn by the manufacturer in 1975 after it was shown to cause agranulocytosis, a condition involving a dangerous decrease in the number of white blood cells, that led to death in some patients. In 1989, after studies demonstrated that it was more effective than any other antipsychotic for treating schizophrenia, the U.S. Food and Drug Administration (FDA) approved clozapine's use but only for treatment-resistant schizophrenia.
Birth Control Side Effects Long Terms Many of the adverse effects of oral contraceptive use reported
in the older literature were found subsequently to be dose related. As a result,
the incidence of side effects has diminished dramatically as the hormonal
content of the pill has plummeted. In the 1960s, the pill had 150 ug of
mestranol and 10 mg of progestin, whereas modem low-dose formulations have 20-35
ug of estrogen and 1 mg or less of progestin. Side effects reported to occur
with oral contraceptive use include headaches, weight changes, mood changes,
changes in libido, vaginal changes, and gastrointestinal problems. A recent
double-blinded, placebo-controlled study found that the incidence of side
effects with low-dose oral contraceptives was not statistically different from
that of the placebo users. The incidence of weight gain, breast tenderness, and
headache was essentially the same in each group.
Pulmonary Embolism Symptoms and Prevention Pulmonary embolism is a condition in which a part of blood clot in a vein breaks away and travels through the heart and into the pulmonary circulatory system. Here the vessels leading from the heart branch like a tree, gradually becoming smaller until finally they form capillaries, the smallest blood vessels. Depending on its size, the clot will at some point reach a vessel through which it cannot pass, and there will lodge itself. The clot disrupts the blood supply to the area supplied by that vessel. The larger the clot, the greater is the area of lung that loses its blood supply, and the more drastic the results to the patient.
FOODS CAUSE OF ALLERGY People may be sensitive to single or to multiple foods. Here again are some foods which are botanically related, so that if a patient is sensitive to one food in this group, he sensitive to the others. Examples of this may be cited in the case of cabbage, Brussels sprouts, and cauliflower. Many of the sea foods and fresh water fish are thus similarly related; so that if a patient is sensitive to one type of fresh water fish, he is likely sensitive to the others. The most frequent allergy-producing foods are common foods, namely, milk, eggs and wheat, fish and nuts. It is unfortunate that this is the case because these are also essential foods, and this avoidance becomes a serious problem in undernourished people and in children of infants. When a patient is definitely sensitive to one or two foods only, it is not difficult for him to realize it himself. The difficulty arises, however, when he is allege to many foods. Under these circumstances he is likely to become confused and then he needs a physician's help. Allergy to a food may be of various degrees of severity. Symptoms of asthma or hives may not arise if only one food is eaten if the sensitivity is mild. However, if a number of such foods are ingested at one time, the symptoms may be pronounced. Another factor which is important in connection with the production of symptoms is the readiness with which a food is absorbed from the gastrointestinal tract. The quicker the absorption, the more rapid will the symptoms develop after eating.

Treacher Collins Syndrome Pictures Treacher–Collins syndrome (TCS), also known as Treacher-Collins–Franceschetti syndrome, or mandibulofacial dysostosis is a rare autosomal dominant congenital disorder characterized by craniofacial deformities, such as absent cheekbones.Treacher-Collins syndrome is found in about 1 in 10,000 births. In a number of cases a genetic origin is described.
This gene controls development of the bones and other structures of the head and neck. When the gene is faulty, the facial bones don't develop as they should in the womb and a baby is born with characteristic facial features. The extent of these abnormalities varies from person to person, but they often cause problems with hearing, breathing and eating.
Breast Cancer Treatment and Therapy Guidelines What about the follow-up after our primary and adjuvant treatment for breast cancer? We know from many good signs that most of the recurrences are found by patients, second most by physicians and almost never by routine tests. Therefore, the official recommendations for follow-up of asymptomatic individuals after primary therapy is that they have history and physicals about every four to six months and that they have annual mammographies. There are no films, scans, tumor markers that are indicated in the follow-up of asymptomatic individuals. So, we usually suggest a history and physical every three to six months and an annual mammography. This is something that is continually under review. It might change, but today, all of the studies that have been done have never been able to show survival benefit for intensive screening with radiographic and blood testing as opposed to just clinical follow-up of these patients.
Metastatic breast cancer. If breast cancer is found to have spread at the time of diagnosis or recurs later after local therapy, we have a situation which cannot be realistically considered to be a curable disease at this point. I think that is important. It is equally important however to recognize that the survival ratio with metastatic breast cancer is very, very variable. If you have metastatic lung cancer or inoperable pancreas cancer, most of these patients are dead in year. Certainly within 18 months. There is almost no survival at two years with a disease like that. Breast cancer is all over the board. The median survival from onset of metastases is probably on the order of two to three years but all of us have patients who have lived 10 years or more in very good physical condition after the development of metastatic disease. So, again looking at the clinical parameters of what the disease-free interval is, what sites are involved, whether the hormone receptors are positive, can help you project somewhat what is going to happen but is a situation with an extremely variable prognosis.
Parkinsons disease treatment guidelines Excitement and tension can cause these symptoms to worsen, as can depression. Depression common among Parkinson’s disease victims, who are understandably upset by their loss of muscle control.
Parkinsons disease Diagnosis
Diagnostic evaluation involves a history, physical examination, and observation of the symptoms. If tremors are the only symptom displayed, tests may be done to rule out the possibility that other disorders are causing the tremors, such as liver disease, multiple sclerosis, chronic alcoholism, or over activity of the thyroid gland.
What is Lobotomy definition Are you looking for lobotomy definition? here is some good list definition for lobotomy on internet.
Lobotomy, in medicine, destruction or removal of the prefrontal lobes of the cortex of the brain. The procedure was popularized by Portuguese psychiatrist Antonio Egas Moniz in 1935 as a means of controlling aggressive or violent behavior—work for which Moniz received the Nobel Prize in physiology or medicine in 1949. The original procedure was modified in 1937 to involve severing almost all the nerve tracts connecting the prefrontal lobes with the rest of the brain. Although the operation was hailed as a major advance in treating severely emotionally ill patients, physicians realized in the late 1940s that many patients were transformed by the lobotomy into inactive individuals without initiative.
Neutralization Therapy Neutralization therapy is an extension of the provocation-neutralization testing procedure in which specified doses of allergen extracts are used by the patient to relieve symptoms. It is also called "symptom-relieving" therapy and "tolerance." Advocates recommend it for both treatment and prophylaxis.
Glaucoma Treatment Guidelines Are you looking for glaucoma treatment guidelines? Glaucoma is an eye disorder in which the optic nerve suffers damage, permanently damaging vision in the affected eye(s) and progressing to complete blindness if untreated. It is often, but not always, associated with increased pressure of the fluid in the eye (aqueous humour). The term 'ocular hypertension' is used for cases having constantly raised intraocular pressure (IOP) without any associated optic nerve damage. Conversely, the term 'normal' or 'low tension glaucoma' is suggested for the typical visual field defects when associated with a normal or low IOP.
Safflower Oil Nutrition Value and Information Safflower (Carthamus tinctorius L.) is a highly branched, herbaceous, thistle-like annual. It is commercially cultivated for vegetable oil extracted from the seeds. Plants are 30 to 150 cm tall with globular flower heads having yellow, orange or red flowers. Each branch will usually have from one to five flower heads containing 15 to 20 seeds per head. Safflower is native to arid environments having seasonal rain. It grows a deep taproot which enables it to thrive in such environments.
Tips for Cancer Prevention What to do
Eat more broccoli, cauliflower, and brussels sprouts. Eat more cabbage-type vegetables. All cabbages and kale are examples. These vegetables protect against cancers of the colon, rectum, stomach, and lung.
Add more high-fiber foods to your diet. Eat more peaches, strawberries, potatoes, spinach, tomatoes, wheat and bran cereals, rice, popcorn, and wholewheat bread. Fiber protects against cancer of the colon.
Choose foods containing vitamin A. Eat more carrots, peaches, apricots, squash, and broccoli. Fresh foods are the best source and are far better than vitamin pills. Vitamin A protects against cancers of the esophagus, larynx, and lung.
Choose foods containing vitamin C. Eat more grapefruit, cantaloupe, oranges, strawberries, red peppers, green peppers, broccoli, and tomatoes. These help fight cancers of the esophagus and stomach.
Practice weight control. Exercise and eat foods low in calories. A good exercise for most people is walking. Obese people have a high chance of getting cancers of the uterus, gallbladder, breast, and colon. Check with your doctor before you start an exercise program or a special diet.
