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 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.
Infantile Eczema (Atopic Dermatitis) Skin eruptions which my occur at any time in life but which usually are found in infants and children may be aczema. The condition at first appears on the face and on the back of the wrists. Later in childhood it may be found in the bends of the elbows and the region back of the knees. At a result of scratching, these break open and oozing takes place. There is severe itchiness, and this constitutes the most disturbing feature of the disease. Allergic factors play a rather important role in this dermatitis. Most of these people have a family history allergy. They may present other allergic manisfestations, such as hay fever or asthma. Indeed, in some instances it is realized that the infant or child cannot tolerate certain foods or sensitive to certain substances in his environment.
Planning a Nutrition Strategy for Wellness Fortunately it is not necessary to be a nutritionist to form a nutrition strategy that works for you. A nutrition plan will work only if it is personalizing your nutrition plan.
Adrenal Insufficiency Causes, Symptoms and Treatment Autoimmune adrenalitis is the most common cause of primary adrenal insufficiency. Adrenalitis caused by tuberculosis was once the most common cause. Autoimmune adrenalitis is sometimes accompanied by other autoimmune endocrine deficiencies, such as thyroid disease, diabetes mellitus, pernicious anemia, hypoparathyroidism, or ovarian failure (Table 14). Recently, AIDS and antiphospholipid syndrome have been cited as additional causes.
Iatrogenic tertiary adrenal insufficiency, a common secondary cause of adrenal insufficiency, results from suppression of hypothalamic-pituitary-adrenal function secondary to glucocorticoid administration. Secondary adrenal insufficiency may also result from pituitary or hypothalamic disease, as described earlier.
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.
Vulvar Disease In addition to inspection, several other diagnostic aids are available. Papanicolaou (Pap) smears of the vulva, although generally not obtained, may be useful for ulcerated lesions. A saline-moistened tongue depressor or similar spatula is used to scrape the lesion for a specimen, which is then smeared on a slide for fixation.
The toluidine blue test is also helpful, particularly for selecting biopsy sites in cases of suspected vulvar dystrophy. The test is carried out by applying a 1% aqueous solution of toluidine blue, which is a nuclear stain, to the entire vulva, allowing 1 to 2 minutes for drying, then gently wiping the excess dye away with a cotton-tipped swab saturated with 1% acetic acid. Areas that retain the blue dye should be biopsied, but nonmalignant ulcers and fissures may stain blue.
What is invasive molar pregnancy An invasive mole (cborioadenoma destruens) is a condition that halfway between a molar pregnancy and a true malignant mole. The molar tissue of ten grows into the muscle of the wall of the uterus, bur under the microscope the cell do not look like malignant molar cells.
For the placenta to implant itself in the wall of the uterus to establish of the normal pregnancy, it must be able to invade the mother’s uterine wall. When trophoblasts start growing abnormally, however, they can become invasive, even highly invasive.
Herpes Symptoms in Men Herpes simplex virus (HSV) affects more than one-third of the world's population. HSV exists as types 1 and 2, which have affinities for different body sites. Ninety percent of infections caused by HSV-2 are genital, and 90 percent of those caused by HSV-1 are oral.
Acute Leukemia Prognosis, Symptoms and Treatment Acute Leukemia is neoplastic disorders characterized by proliferation of immature hematopoietic
precursor cells in the bone marrow, and later in the peripheral blood and
other organs and tissues. If untreated, death usually occurs within six months
of diagnosis. Increase risk is associated with the following:

Cantaloupe calories per ounce and nutrition facts
Are you looking for Cantaloupe calories per ounce and nutrition facts? Cantaloupe (also cantaloup, mushmelon, muskmelon, rockmelon or spanspek) refers to a variety of Cucumis melo, a species in the family Cucurbitaceae which includes nearly all melons and squashes. Cantaloupes range in size from 0.5 to 5.0 kilograms (1.1 to 11 lb). Originally, cantaloupe referred only to the non-netted orange-fleshed melons of Europe; however, in more recent usage it has come to mean any orange-fleshed melon (C. melo).
Cantaloupes have been linked to listeriosis illness caused by Listeria bacteria.
