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
What is Mineral Nutrient Mineral are simple but important nutrients. As inorganic compounds they lack the complexity of vitamins, but they fulfill a variety of functions. For example, sodium and potassium affect shifts n body fluids, calcium and phosphorus contribute to the body's structure, iron is the core of hemoglobin (an oxygen-carrying compound in the blood), and iodine facilitates production of thyroxine ( hormone that influences metabolic rate).
There are 20 to 30 important nutritional minerals. Compared with the energy nutrients and water, minerals should be consumed in small amounts. Minerals that are present in the body and required in large amounts (more than 100 mg [1/50 teaspon] per day) are called major minerals or prominence, calcium, phosphorus, potassium, sulfur, sodium, chloride, and magnesium. Major minerals contribute from 60% to 80% of all inorganic material in the human body.
Genetics of Behavior Behavior Genetics is a “science that combines aspects of psychology, psychiatry, physiology and genetics,” the goal of which “is to clarify the role that genetic factors play in the determination of behavior.” The term genotype refers to the total set of genes present in an individual at the time of conception and coded in the DNA. The physical manifestations of a particular genotype ate designated by characteristics that specify a specific Phenotype. Examples of phenotypes include eye color, height, blood type, language and hair type. As evident by the examples presented, phenotypes are not only genetic but may also be acquired (i.e. influenced by the environment) or a combination of both. It is likely that most psychiatric disorders are the result of a combination of genetics and environment influences)
Investigators who study the etiological implications for psychiatric illness may explore several risk factors. Studies to determine if an illness is Familial compare the percentages of family members with the illness to those in the general population of in a control group of unrelated individuals. These studies estimate the prevalence of psychopathology among relatives and make predictions about the predisposition to an illness based on familial risk factors. Schizophrenia, bipolar disorder, major depression anorexia nervosa, panic disorder and alcoholism are examples of psychiatric illness in which familial tendencies have been indicated.
Gluten intolerance symptoms in children Are you looking for gluten intolerance symptoms in children? Gluten is composed of the sticky storage proteins found in wheat. Gluten-sensitive enteropathy (GSE) can range from mild inflammation of the mucosa of the small intestine to severe coeliac disease. The term gluten-sensitive is applicable when a probable diagnosis of GSE is made based on conditions such as dermatitis herpetiformis. However, GS may be used as the diagnosis in ambiguous situations when other conditions may be possible. For example, wheat allergies to gluten can result in anaphylaxis while others may be difficult to diagnose because of some of the cryptic inflammatory properties of wheat proteins. The term 'gluten sensitivity' is typically applied when diagnostic testing is not done because of prolonged gluten-free diet and/or refusal of gluten-challenge prior to biopsy. The gluten-sensitive designation may not be appropriate in all cases, as wheat allergies are often directed toward albumins or globulins of wheat, or the person may have a sensitivity to proteins commonly found with wheat products (e.g. fungal amylase or bread-yeast mannins). Therefore diagnostic criteria are preferred. The relationship between gluten and these various sensitivities is complex. For gluten enteropathy, T-cell reactivity is almost entirely restricted to prolamin-glutelin/species within the grass tribe Triticeae, and especially α-gliadins of wheat. For a tiny minority of GSE, inflammatory responses may extend to cover oats. Gluten allergies may extend over wide taxa or may be specific to certain wheat proteins and allergies may include oats.
Acai Berry Diet Pills Review and Side Effect Are you looking for Acai Berry Diet Pills Review and Side Effect? Acai berry is actually derived from tree pulp. The tree is similar to a palm tree and grows as tall as 60 feet. The tree sprouts hundreds of deep purple pulps that are similar to berries in size and color. Once harvested, the pulp is thick like that or orange pulp. The pulp is then processed to accommodate capsules, juice, and even powder. Almost even well -known beverage companies including Coca-Cola, Pepsi, and even Anheuser-Busch want a piece of the acai berry and here is why. The acai berry is almost entirely comprised of antioxidants. These are the same antioxidants that are responsible for cancer prevention, anti- aging , and improvement in brain function. Overall, the acai berry is a super fruit with the ability to remedy ailments and improve physical appearance.
What is a missed abortion A missed abortion is a miscarriage in which the fetus dies but the uterus does not expel the pregnancy tissue immediately. Before ultrasound was available, it was thought this happen only occasionally. Now we know that in many pregnancies the fetus stop growing and dies and woman will not star bleeding or cramping until much later. Without ultrasound, she would not have known for several weeks that the pregnancy was not still growing in a normal way. She would be unaware of the condition until she finally started the typical bleeding of miscarriage.
What is Pescatarian Definition and Recipes Are you looking for about what is pescatarian? and what are pescatarian recipes? A pescatarian is a person who refrains from eating land animals and birds, but includes fish, mollusks, and crustaceans in addition to fruits, vegetables, plants, legumes, nuts, and grains. This is a common form of “vegetarianism” and is generally considered a very healthy diet. It can also be a stepping stone to full vegetarianism. Pescatarians can enjoy lowfat protein sources that are high in fish oils, which contain Omega 3 fatty acids—the “good fats” that reduce inflammation.

Medical abbreviations list Are you looking for medical abbreviations list?
Abbreviations are used very frequently in medicine. They boost efficiency as long as they are used intelligently. The advantages of brevity should be weighed against the possibilities of crypticness (making the communication harder for others to understand) and ambiguity (having more than one possible interpretation). Certain medical abbreviations are avoided to prevent mistakes, according to best practices (and in some cases regulatory requirements); these are flagged in the list of abbreviations used in medical prescriptions.

What is Morgellons Disease Morgellons (also called Morgellons disease or Morgellons syndrome) is a name that was given in 2002 by stay-at-home-mom Mary Leitao to a proposed condition characterized by a range of cutaneous (skin) symptoms including crawling, biting, and stinging sensations (formication); finding fibers on or under the skin; and persistent skin lesions (e.g., rashes or sores). Most doctors, including dermatologists and psychiatrists, regard Morgellons as a manifestation of known medical conditions, including delusional parasitosis.
Bones and Muscles The bones of the human body, securely attached together by ligaments, form the skeleton or framework of the body. The body tissue, organs, and systems are located either inside the cavities formed by the skeleton or around it. The skeleton is the framework that holds everything in place. Also it source of attachment for many of the organs.
Gluten Free Diet Plan Weight Loss A gluten-free diet is a diet that excludes foods containing gluten. Gluten is a protein found in wheat (including kamut and spelt), barley, rye, malts and triticale. It is used as a food additive in the form of a flavoring, stabilizing or thickening agent, often as "dextrin". A gluten-free diet is the only medically accepted treatment for celiac disease, the related condition dermatitis herpetiformis, and wheat allergy.
How to Reduce Fever Fast in a child Fever in Infants and Children
A normal temperature is about 98.6°F (37°C) when taken orally (in your child’s mouth) and 99.6°F (37.5°C) when taken rectally (in your child’s bottom). Many doctors define a fever as an oral temperature above 99.5°F (37.5°C) or a rectal temperature above 100.4°F (38°C).
