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
New Treatments for Newborn Neurology Hypoxic ischemic injury is a major cause of mortality and morbidity.
Usually it is a combination of hypoxia and ischemia that basically results in
decreased supply of oxygen to the tissue, and that’s the cause of it.
Hypercapnia and acidosis also contribute significantly to the development of
hypoxic ischemic injury. There’s also biochemical and cellular level changes
that occur, such as increased glycolysis. You have lactic acid production, you
have decreased ATP production as well and you have free radical production, and
therefore accumulation of extracellular potassium and intracellular calcium.
They occur frequently in the different parts during the pregnancy and the labor
and delivery process that accounts for this. Twenty percent is noted during the
antepartum, about 35% is noted in the intrapartum period and there are other
factors, such as combination factors, both intrapartum and antepartum that
occurs about 35%. And post-natally only 10%. Obviously what we mean by
postnatal, it means after the delivery. It occurs in up to 1.5% of live birth
infants, and the incidence is greater … it the child is greater than 36 weeks
age of gestation and therefore more or less a full term child - full term being
37 to 40 weeks age of gestation - the incidence is quite low. It’s only 9%.
However, in children less than 28 weeks or between 24 weeks to 35 weeks, the
incidence can be as high as 80%.
Treatments for Endometriosis Adenomyosis is endometriosis in the endometrium, specifically in the musculature, and if it is found below the basement membrane. Endometriosis has been found in an estimated ten percent of the general population. This was found a long time ago when we did tubal ligations on patients and saw endometriosis in normal fertile patients. However, endometriosis has been found in about twenty-five to thirty percent of infertile patients undergoing laparoscopy. So what are Treatments for Endometriosis?

Symptoms bowel cancer Are you looking for symptoms bowel cancer? Colorectal cancer, commonly known as bowel cancer, is a cancer caused by uncontrolled cell growth (neoplasia), in the colon, rectum, or vermiform appendix. Colorectal cancer is clinically distinct from anal cancer, which affects the anus.
Colorectal cancers start in the lining of the bowel. If left untreated, it can grow into the muscle layers underneath, and then through the bowel wall. Most begin as a small growth on the bowel wall: a colorectal polyp or adenoma. These mushroom-shaped growths are usually benign, but some develop into cancer over time. Localized bowel cancer is usually diagnosed through colonoscopy.
Managing Stress Behaviors Stress is not something that you can run from or wish into nonexistence. To control stress, you must meet it head on and use as many resources as you can to insure that your coping skills are fine-tuned and ready to help you. In planning your personal strategy for stress success, you should consider the following :
Mesenteric Ischemia Mesenteric ischemia is classified as acute mesenteric ischemia (AMI) chronic mesenteric ischemia (CMI). AMI is subdivided into occlusive and nonocclusive mesenteric ischemia. Occlusive mesenteric ischemia results from either thrombotic or embolic arterial or venous occlusion. Approximately 80% of cases of AMI are occlusive in etiology, with arterial emboli or thromboses in 65% of cases and venous thrombosis in 15%. Arterial occlusions result from emboli in 75% of patients and in situ thrombosis cause the remaining 25%. NOMI is caused by low perfusion states and is responsible for 20% of AMI.
Recognizing Anorexia and Bulimia and Treatment Anorexia Nervosa A young woman, competitive and perfectionistic by nature, determines that her weight (and appearance) is unacceptable. She begins to disregard her appetite, and her food consumption virtually ceases. This young man may be seen by her friends as active and intelligent and simply dieting and exercising with an unusual degree of commitment. Eventually, however, they observe that her food consumption has nearly stopped. Her weight loss has continued beyond the point that is pleasing-at least to others. Still, her activity level remains high. When questioned about her weight loss, she says that she still needs to lose more weight.
This person is suffering form medical condition called anorexia nervosa. This self-induced starvation is life-threatening in 5% to 20% of cases. The stunning amount of weight that some anorexic people lose-up to 50% of their body weight-eventually leads to failure of the heart, lungs, and kidneys.
Antioxidant vitamins Three vitamins are classified as antioxidants – vitamins C, E, and beta-carotene. Antioxidants are protective substances because they help neutralize the activity of free radicals. Free radicals are naturally produced chemicals that arise from normal cell activity. When ever the body uses oxygen or is exposed o a toxin, such as cigarette smoke, it forms free radicals. These unstable chemicals can damage cells throughout the body. They may damage a cell's DNA in ways that lead to cancer, may interact with cholesterol in the bloodstream and form oxidized Low-density lipoprotein (LDL) may cause cataracts and rheumatoid arthritis, and may be factor in the physiological changes associated with the aging process. Anything that interferes with the destructive effects of free radicals offers a health advantage. Vitamins C, E, and beta-carotene are believed to prevent the oxidation of cholesterol and other molecules linked to the diseases mentioned previously, most notably heart disease and cancer. A common cooking practice illustrates this antioxidant effect: some foods like bananas, peaches, apples, and potatoes quickly turn brown when exposed to air. However, when such foods are dipped in lemon or orange juice, the vitamin C in the juice acts as an antioxidant and prevents browning.
Paleo Diet Plan for Weight Loss The Paleo Diet is a way of eating that is very similar to the way our ancestors allegedly ate during the Paleolithic period, which was about 10,000 years ago. According to the Paleo Diet creator Dr. Loren Cordain the foods suggested in the Paleo Diet are high in the nutrients our bodies need to stay fit, and low in those that contribute to weight gain and illnesses related to too much weight gain.
The creators of the Paleo diet and recipes contend that the human body is genetically made to eat the way our ancestors did prior to the industrialization of agriculture.

Angina Pectoris Causes The most common symptom of coronary artery disease is angina pectoris, chest pain caused by insufficient oxygen getting to the muscles of the heart. Angina is usually described as a tightness, pressure, or dull aching pain under the breastbone and on the left side of the chest. Often it is described as "feeling like someone's sitting on my chest." The pain may radiate from the chest to the left arm or the left side of the jaw, and occasionally to the back.
The symptoms of angina are experienced in different ways by different people, but an individual usually experiences the same symptoms every time an attack occurs. Many experience sweating, shortness of breath, chills, or nausea during an attack. Others have no symptoms but a mild chest discomfort. Angina usually resolves five to ten minutes after exertion stops.
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

problems are commonly associated stressors. Abdominal pain can be related
to school absenteeism and may be a sign of depression.
TLC Diet Menu plan and GuideLines The Therapeutic Lifestyle Changes (TLC) Diet was devised by the U.S. government's National Cholesterol Education Program (NCEP) to give guidance to people who have blood cholesterol problems. The TLC Diet doesn't have a recommendation for how many calories people with cholesterol problems should eat daily because calories don't affect cholesterol levels directly.
