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
Misophonia symptoms and treatment What is Misophonia definition? Misophonia – literally the hatred of sound -can be defined as a hypersensitivity to background sounds or visual stimuli that are generally ignored by other people. More importantly than the individuals inability to block out the offending stimuli or “trigger” is the acute negative emotional response experienced as a direct result of being in contact with a trigger.
Misophonia commonly occurs along with hyperacusis and/or tinnitus, but can appear by itself. One of the tools we use to treat misophonia at AC Associates is called Tinnitus Retraining Therapy (TRT). TRT recognizes the specific involvement of various components of the auditory pathways of the nervous system in occurrences of tinnitus, hyperacusis and misophonia. For treatment of misophonia, TRT uses a method based on the active removal of conditioned reflexive responses to sound, allowing patients to feel like themselves again.
Crystal arthritis We are going to start out with gout, which is a thing to remember, it is a different disease for both male and female. Men tend to present at a younger age because of the association with uric acid and antigen levels in the blood. Some are between the ages of 35 and 55, is the average onset of gout in a male patient. Usually it presents as an acute podagra, which is the great toe or possibly a knee or an ankle depending upon the saturation of the soft tissue with uric acid.
Celiac disease symptoms diagnosis Are you looking for celiac disease symptoms diagnosis? Celiac disease is a genetic disorder that affects your digestive system and damages your small intestines. If you have celiac disease, your body is sensitive to gluten and your immune system reacts abnormally to foods you eat that contain gluten. Gluten is a protein found in foods and products that contain certain grains, such as wheat, oats, barley and rye.
Ovarian Cancer Staging and Treatment Are you looking for article about ovarian cancer staging and treatment? Here is good stuff about ovarian cancer staging and treatment.
The FIGO staging classification scheme for ovarian cancer is outlined in the box, page 42. The staging of advanced disease (spread throughout the abdomen) may be obvious to most physicians, but it is important for a surgeon to be meticulous in the staging of early ovarian cancer. In one study it was found that one third of patients referred with stage I or stage II disease were actually found to have stage III disease when the appropriate staging operation was performed. Similar results have been reported by other researchers.
Psoriasis Symptoms and Treatment Psoriasis is common, affecting 1.5-2.0% of the population. It affects all ages, with bimodal peaks of incidence at ages 20-30 and 50-60 years. Plaque-type psoriasis is easily identified by its discrete round orange-red plaques with silver scale on the scalp, elbows, knees, or trunk. When psoriasis appears as intertriginous, guttate, or nail-limited psoriasis, the diagnosis can be challenging.
Etiology. Psoriasis exhibits abnormalities of epidermal proliferation and migration of inflammatory cells, resulting in accelerated epidermal turnover time. Psoriasis, particularly extensive psoriasis, has a strong genetic component. Exacerbants of psoriasis include stress, probably alcohol, many drugs, infection, and steroids.
Symptoms of endometriosis Are you looking for symptoms of endometriosis? here is some good article about symptoms of endometriosis.
Ten percent of women will develop endometriosis, characterized by the presence of endometrial tissue at sites outside the uterine cavity. The ectopic endometrial cells cause cyclical dysmenorrhea. The most common sites are the ovaries, posterior cul-de-sac, uterosacral ligaments, posterior broad ligament, and anterior cul-de-sac. The uterine serosa, rectovaginal septum, cervix, vagina rectosigmoid, and bladder are less frequent locations.
Stages and Effects of Pyrexia and Hyperpyrexia A pyrexia is a body temperature between 37.60 and 400C and hyperpyrexia is a temperature > 400C. They are conditions in which the thermoregulatory mechanisms are intact but the body temperature is high. Infection s the most common cause of pyrexia and sepsis of hyperpyrexia but there are other causes. A number of drugs have been associated with pyrexia, e.g. diuretics, antiseizure therapy, analgesics, antiarrhythmics and antibiotics. Other causes of pyrexia include neoplasm, surgery, acute myocardial infarctions, heart failure, haemolysis (seen in reactions to blood transfusions) and hyperthyroidism.
Enterohaemorrhagic Escherichia Coli EHEC Escherichia coli O157:H7 is an enterohemorrhagic strain of the bacterium Escherichia coli and a cause of foodborne illness. Infection often leads to hemorrhagic diarrhea, and occasionally to kidney failure, especially in young children and elderly persons. Transmission is via the fecal-oral route, and most illness has been associated with eating undercooked, contaminated ground beef, swimming in or drinking contaminated water, and eating contaminated vegetables.
Somatoform Disorders Symptoms and Classification Somatization is defined as the transference of mental experiences and sense into bodily symptoms. Somatzations disorder is characterized by presence of recurrent and multiple, frequently changing somatic complaints of several years duration, for which medical attention has been sought, but these apparently are not due to any physical disorder.
Somatoform disorders are characterized by physical symptoms suggesting medical disease but without demonstrable organic pathology or known pathophysiological mechanism to account for them. They are classified as mental disorders because there is either evidence or strong presumption that physiological factors are the major cause of symptoms or not understandable by existing laboratory procedures. Three central features of somatoform disorders are as follows:

Emphysema Life Expectancy Stages Emphysema occurs when the air sacs in your lungs are gradually destroyed, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease (COPD). Smoking is the leading cause of emphysema.
As it worsens, emphysema turns the spherical air sacs — clustered like bunches of grapes — into large, irregular pockets with gaping holes in their inner walls. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream.
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.
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
