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
Nephritis Symptoms and Treatment Nephritis is a disorder characterized by inflammation of the glomeruli of the kidneys. The glomeruli are tiny coiled blood vessels through which the liquid portion of the blood is filtered as it enters the outer structure of the kidneys. There are about one million of these tiny blood vessels in each kidney. The fluid from the blood passes from them into many little ducts called tubules. Water and various substances are secreted into and absorbed from the liquid in the tubules. The final product of this passage of filtered fluid from the glomeruli through the tubules to the uterus and then to the bladder is urine. It contains the excess fluid and waste products produced by the body during normal functioning.
Arrhythmias Treatment and Types A disturbance in the rhythm of the heart is termed arrhythmia and can range from a mild “skipped beat” to a life-threatening failure to pump. The later is called ventricular fibrillation, and it is the most common cause of cardiac arrest, in which the heart suddenly stops beating. Death can follow in minutes unless medical help is provided immediately. People who have had a heart attack or who are elderly are at a much higher risk of developing a life-threatening arrhythmia.
In ventricular fibrillation, the heart’s electrical activity becomes disordered. As a result, the heart’s lower (pumping) chambers rapidly contract in an unsynchronized way. In effect, the ventricles flutter rather than beat, and the heart pumps little or no blood. Symptoms may include palpitations, lightheadedness, chest discomfort, shortness of breath, or loss of consciousness. If a more normal rhythm is not restored within three to five minutes, the patient will suffer brain and heart damage and will die.

Colon Rectum Cancer Symptoms and Therapy Cancer of the colon (large intestine) and rectum is the second leading cause of cancer-related deaths in the United States. Each year it claims an estimated 48,000 lives, and produces about 107,000 new cases—more than any other kind of cancer except skin cancer. It afflicts men and women about equally. The five-year survival rate from this form of cancer, usually after surgery, is about 90 percent where the cancer was localized about 65 percent where there was regional involvement. The death rate from colon and rectum cancer has decreased significantly over the past 20 years due to, among other factors, improved treatments and earlier diagnosis.
Best countries for Plastic Surgery Are you looking for Best countries for plastic surgery?
Cosmetic plastic surgery includes surgical and nonsurgical procedures that reshape normal structures of the body in order to improve appearance and self-esteem. Healthy individuals with a positive outlook and realistic expectations are appropriate candidates for cosmetic procedures. Plastic surgery is a personal choice and should be done for yourself, not to fulfill someone else's desires or to try to fit an ideal image. Because it is elective, cosmetic surgery is usually not covered by health insurance.
High Protein Foods List Are you looking for high protein foods list? here is some list for high protein foods.
Protein is an essential nutrient that is important to your health. Protein consists of chains of amino acids that are used by our bodies to grow muscles, hair, nails, skin and internal organs.
Diets rich in high protein foods are often recommended for athletes and body builders. In addition, many weight loss diets such as the Atkins diet prescribe a high protein, low carb diet.
Although protein is an essential nutrient, some research suggests that too much protein can increase the risk of developing heart disease, stroke, kidney stones and osteoporosis.
Abdominal Pain Symptoms and Treatment A common primary care problem, especially among females, that is most oftenbenign but can be related to serious diagnoses. Functional pain is the
most common recurrent form of pain. Generally a diagnosis of exclusion, it is
defined as nonorganic pain related to everyday stress. School, peer, and family
problems are commonly associated stressors. Abdominal pain can be related
to school absenteeism and may be a sign of depression.
Heat Stroke Long Term Effects Are you looking for heat stroke long term effects? here is some good article about heat stroke long term effects.
Heat stroke is a form of hyperthermia, an abnormally elevated body temperature with accompanying physical symptoms including changes in the nervous system function. Unlike heat cramps and heat exhaustion, two other forms of hyperthermia that are less severe, heat stroke is a true medical emergency that is often fatal if not properly and promptly treated.
Transient ischemic attacks Symptoms and Treatment Transient ischemic attacks (TIAs) are neurogical deficits (such as loss of vision in one eye, inability to speak, paralysis, or weakness of one side of the body) of sudden onset that last for less than 24 hours. Although they are symptomatically similar to minor strokes, they do no discernible lasting damage to brain function.
The major importance of TIAs is their role as a predictor of stroke. When a person describes a “light stroke”, it is often a TIA that is meant. If left untreated, TIAs can indeed lead to major strokes, with permanent damage to all parts affected.
Lichen Sclerosus Lichen sclerosus is an atrophic, shrinking disease that usually occurs in postmenopausal women. The main symptom, if any, is pruritus. It can appear in children but remits after the menarche. The skin thins to a dry, shiny, fragile, finely wrinkled, parchment-like appearance and the external genitalia contract and lose their shape and definition. White patches fuse into a symmetric, "keyhole" pattern, often encompassing the perianus. Telangiectasia and mid-line skin "splits" are common. Histologically the epidermis is thin with flattened rete pegs. The dermis is edematous and hyalinized, with a loss of elastic fibers. There is a chronic inflammatory infiltrate in the lower dermis.
Reboot diet recipes and reviews are you looking for reboot diet recipes and reviews? Joe Cross goes through 60 days of juice fasting, a so called "Reboot" to reset his body's system, and naturally looses an enormous amount of kilos, but this can obviously not be recommended without a doctor's supervision. So according to Reboot Your Life's website a 5 day juice fast is recommended, or for a bit of a more humane version a diet with light meals and juice in combination.
Blood type diet chart and list Are you looking for blood type diet chart? The blood type diet is a diet advocated by Peter D'Adamo, a naturopathic physician, and outlined in his book Eat Right 4 Your Type. D'Adamo's claim is that ABO blood type is the most important factor in determining a healthy diet, and he promotes distinct diets for people with O, A, B, and AB blood types.
One criticism of D'Adamo's hypotheses and recommendations claims that he provided inadequate evidence. For example, his first book, Eat Right 4 Your Type, published in 1997, contains only a bibliography. While his subsequent books have provided thorough references for the classifications of various foods within his categories of "beneficials", "neutrals" and "avoids", his specific process and reasons for reaching these conclusions of classification remain undocumented.
Trigeminal Neuralgia Treatment Guidelines Are you looking for trigeminal neuralgia treatment guidelines? Trigeminal neuralgia (TN), tic douloureux (also known as prosopalgia, the Suicide Disease or Fothergill's disease) is a neuropathic disorder characterized by episodes of intense pain in the face, originating from the trigeminal nerve. It has been described as among the most painful conditions known. It is estimated that 1 in 15,000 people suffer from TN, although the actual figure may be significantly higher due to frequent misdiagnosis. In a majority of cases, TN symptoms begin appearing after the age of 50, although there have been cases with patients being as young as three years of age. It is more common in females than males.
