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
Stomach Pain After Eating in Children Chronic and recurrent abdominal pain is common in children and the term refers to pain for which a specific cause (by history, physical examination, or laboratory tests) has not been determined. It occurs in 9 to 15 percent of all children. In boys, pain is most common between ages 5 and 6 years. Girls have pain most commonly between 5 and 6 years and 9 and 10 years.
Children often complain of stomach ache (pain in the tummy). It can be a sign of illness, but often a child will have pain, but not be unwell. Some of the children who have abdominal pain will be having a difficult time, perhaps at home, perhaps at school, but many children with strong pain do not seem to be stressed or unwell. Research has shown that up to 10% of children have abdominal pain which comes and goes. An illness causes the pain in only about 5% of these children.
HCG Diet Plan Phase 1 Are you looking for HCG Diet Plan Phase 1? The Homeopathic HCG diet plan does not need to be mixed.

Pulmonary Hypoplasia and Congenital Renal Anomalies Caroline May, Anne Greenough
Arch Med Sci 2006; 2, 1: 6-9
The association of pulmonary hypoplasia with bilateral renal agenesis is well
recognised. It is important, however, for clinicians to be aware that pulmonary
hypoplasia does occur with other congenital renal anomalies and worsens the
Coronary Artery Disease Treatment Guidelines It can be difficult to determine whether chest pain is caused by angina. Whenever a person develops symptoms that could be angina, a complete medical evaluation is needed to determine whether coronary artery disease is present and, if so, how severe it is (see also chapter 7). The individual's medical history and descriptions of the pain, actions that cause the pain, and actions that make it better may raise a doctor's suspicion of coronary artery disease, but these factors are not sufficient for actual diagnosis. Likewise, physical examination and blood tests may show that the patient is at risk, but cannot actually diagnose the condition.
An electrocardiogram may or may not show changes of cardiac ischemia. An exercise electrocardiogram, a ''stress test'' done while a person is performing a specific amount of exercise, is more likely to demonstrate whether coronary disease is present. A particular change in the electrocardiogram during exercise can demonstrate that coronary artery disease is present. Even an exercise electrocardiogram is not 100 percent reliable in diagnosing coronary artery disease.

Family Health Nursing “Family health nursing is the practice of nursing directed towards maximizing the health and well-being of all individuals within a family system. It incorporates two views of family; family as a unit of care and family as a system existing within larger system. Levels of intervention are individuals the personal, the family system, and the environmental level. The goals of the family health nursing include optimal functioning for the individual and for the family as a unit.”
The family as a unit of care means that the entire family is the recipient of nursing intervention. This view point recognizes the mandate in the standards of community health nursing’s practice that identifies clients as individuals, families and communities. In contrast, the family as context recognizes the impact the family has on an individual. This viewpoint underscores the need to understand the family environment in which the individual exists.
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.
Downs syndrome Symptoms and Prevention Down’s syndrome is a congenital (present at birth) disorder characterized by varying degrees of mental retardation and a variety of physical abnormalities.
Down’s syndrome Causes
Normally, each cell in the human body has 46 chromosomes; the cells in someone with Down’s syndrome, however, have 47. In ways that are as yet unknown, the presence of the extra chromosome causes all of the unusual characteristics of Down’s syndrome. In 95 percent of cases, the condition is called trisomy 21 (because the extra chromosomes is attached to the twenty-first pair of chromosomes), and the mistake in genetic coding is one that apparently could happen to anyone. In five percent of cases, the syndrome is caused by a defect that is believed to run in families.
New Treatments for Epididymitis The epididymis is located along the posterior border of the testicle with the head. Epididymitis is an inflammation of the epididymis that causes pain and swelling of the epididymis and often of the adjacent testicle. It may be accompanied by abdominal pain and fever. It is usually seen in young men but may occur at any age.
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:
Guidelines for Exercise in the Cold Problems related to exercise in cold weather include frostbite and hypothermia (abnormally low body temperature). Frostbite can lead to permanent damage loss of a body part from gangrene. This can be prevented by adequately protecting exposed areas, such as fingers, the nose, ears, facial skin, and wrists. A stocking hat is preferable for two reasons: (1) blood vessels in the scalp do not constrict effectively, so a significant amount of heat is lost if a head covering is not worn, and (2) a stocking-type hat can be pulled down to protect the ears. In very cold or windy weather, you can use surgical or ski masks and scarves to keep facial skin warm and to moisten and warm inhaled air. All exposed or poorly protected flesh is vulnerable to frostbite when the temperature is low and the wind chill high.
Retrograde uterus pregnancy and fertility What is retrograde uterus definition?A retroverted uterus (tilted uterus, tipped uterus) is a uterus that is tilted backwards instead of forwards. This is in contrast to the slightly "anteverted" uterus that most women have, which is tipped forward toward the bladder, with the anterior end slightly concave.
Between 1 in 3 and 1-in-5 women (depending on the source) has a retroverted uterus, which is tipped backwards towards the spine.
