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

Hernia Symptoms and treatment A hernia is an abnormal protrusion of part of an organ through the tissues that normally contain it. In this condition, a weak spot or opening in a body wall, often due to laxity of the muscles, allows part of the organ to protrude. A hernia may develop in almost any part of the body; however, the muscles of the abdominal wall are most commonly affected.
Types of hernias
A hernia can be congenital (present at birth) or acquired (often the result of stress or strain on the body wall). Although there are many types of hernias, the following are common :
Umbilical hernia-protrusion of a loop of intestine into the groin (where the folds of abdominal flesh meet the thighs). This type of hernia, which accounts for about 75 percent of all abdominal hernias, is often the result of increased pressured in the abdomen because of lifting, coughing, or straining.
Scrotal hernia-an inguinal hernia that has passed into the scrotum (the sac containing the testes).
Femoral hernia-protrusion of a loop of tissue into the femoral canal, which carries nerves and blood vessels from the abdomen into the upper thigh/groin area. This type of hernia is more common in women than in men.
Incisional hernia-a hernia that occurs at the site of a surgical incision. This type of hernia is often due to strain on healing tissues due to excessive muscular effort, lifting, coughing, or extreme pressure.
Hiatal hernia-protrusion of part of the stomach through the diaphragm and into the chest.
Normal Sleep Patterns Sleep duration and quality vary widely among persons of all age groups. One
person may gain adequate rest with 4 hours of sleep, whereas another requires 10
Thyroid Cancer Symptoms and Treatment hyroid carcinoma is common in all age groups, and it is especially in patients who have received any radiation therapy to the face, neck, or upper chest. It is rarely associated with functional abnormalities. Papillary carcinoma is the most common and least aggressive thyroid malignancy. Pure papillary or mixed papillary-follicular carcinoma represents about 70% of all thyroid cancers. Follicular carcinoma represents about 15% of thyroid malignancies but is more likely to have distant metastases. Papillary and follicular thyroid carcinomas are classified as differentiated thyroid carcinoma. Medullary thyroid carcinoma represents less than 5% of thyroid cancers and tends to metastasize locally. Of all cases of medullary thyroid cancer, about one-third are sporadic, one-third are familial occurrences, and another third are associated with multiple endocrine neoplasia type II. Anaplastic thyroid carcinoma represents only about 1% of thyroid malignancies. Other malignancies involving the thyroid include lymphomas and metastases (especially melanoma, breast, renal, and bronchogenic carcinomas).
Drug Classification Drugs are commonly classified according to the physiological effect they have. Categories include stimulants, depressants, hallucinogens, narcotics, and inhalants. Two other types are also important. First, designer drugs are manufactured to mimic the effects if drugs found in the previously mentioned categories. Designer drugs usually are not illegal because their chemical formula has been altered from the original drug. The other drug, marijuana, is difficult to classify but is usually included as a hallucinogen. Depending on the dose, marijuana can mimic a variety of substances found in other categories.
Whole food diet plan and recipes A whole foods diet is a basic, simple way of eating that is just as it sounds. Meals in the diet are composed of whole foods that are unprocessed or as minimally processed as possible. Another way of defining a whole food is put forth by Beatrice Trum Hunter, author of "A Whole Foods Primer." Hunter says that whole foods have "nothing added and nothing taken away." That is, they are as close to their natural state as possible. The School of Medicine at Texas Tech University suggests that whole foods diets are especially suitable for people with obesity or hypertension.

Best osteopathic medicine schools in USA Osteopathic medicine is a branch of the medical profession in the United States. Osteopathic physicians, known as DOs, are licensed to practice medicine and surgery in all 50 states and are recognized in forty-seven other countries, including most Canadian provinces.
Frontier physician Andrew Taylor Still founded the profession as a radical rejection of the prevailing system of medical thought of the 19th century. Still's techniques relied heavily on the manipulation of joints and bones to diagnose and treat illness, and he called his practices "osteopathy". By the middle of the 20th century, the profession had moved closer to mainstream medicine, adopting modern public health and biomedical principles. American "osteopaths" became "osteopathic physicians", gradually achieving full practice rights as medical doctors in all 50 states, including serving in the US armed forces as physicians.
Teenage Acne Treatment Girls Are you looking for teenage acne treatment for girls? Acne is caused when a hair follicle get clogged with an oil called sebum and skin cells. Skin bacteria thrive and multiply in sebum, causing inflammation. Some acne consists of simple blackheads and whiteheads. Inflammation within the pore causes a pimple (also called a “papule”) or a pus-filled pimple (“pustule”), depending on how deep it is. If it’s really deep, it can cause a painful cyst and scarring.
Exactly who does smoking affect baby Cigarette smoking produces a number of abnormalities in a mother’s body. First, cyanide (a strong poison) is produced from smoking. This by product from smoking goes directly to your tissue and to the tissue of your baby, producing hypoxia (lack of oxygen) in the individual cell. In addition to this, nicotine causes constriction of the boob vessels of your body, decreasing the amount of blood flowing through the placenta and adding to the hypoxia produced by the cyanide.
Symptoms of Angina and Treatment with Healthy Food and Diet Angina is often experienced as a pain in the chest, frequently after running
up a flight of stairs, but in extreme cases after getting out of a chair. It is
brought on by an in adequate supply of oxygen via the blood to the heart muscle.
Over many years, arteries begin laying down sticky deposits, which harden and
eventually cause a narrowing within the blood vessels.
Typical symptoms include pain in the centre of the chest, which
sometimes spreads to the neck/jaw area and down the left arm. The pain may also
be accompanied by breathlessness, feeling faint, sweating and/or nausea. If you
have these symptoms, seek medical attention as a matter of urgency.
