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
Detached retina causes and Treatment Normally, the retina is firmly attached to the choroid, and underlying layer of tissue that is rich in blood vessels. If blood or other fluid collects between the retina and the choroid, the retina may become partially or totally detached. Fluid from the vitreous cavity (the fluid-filled space behind the lens) may penetrate beneath the retina because of a small hole in the retina. Fluid leaking out of certain blood vessels in the eye may also penetrate beneath the retina to cause detachment.
Flexeril dosage and usage Flexeril (cyclobenzaprine) is a muscle relaxant. It works by blocking nerve impulses (or pain sensations) that are sent to your brain. Flexeril is used together with rest and physical therapy to treat skeletal muscle conditions such as pain or injury. Flexeril may also be used for other purposes not listed in this medication guide.
Calculate bmi for teenage girls Calculate Your Body Mass Index
Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women.
Exactly who does smoking affect baby Cigarette smoking produces a number of abnormalities in a mother’s body. First, cyanide (a strong poison) is produced from smoking. This by product from smoking goes directly to your tissue and to the tissue of your baby, producing hypoxia (lack of oxygen) in the individual cell. In addition to this, nicotine causes constriction of the boob vessels of your body, decreasing the amount of blood flowing through the placenta and adding to the hypoxia produced by the cyanide.
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.
Acute Abdomen Symptoms and Medications Clinical evaluation of abdominal pain
Onset and duration of the pain
The duration, acuity, and progression of pain should be assessed, and the exact location of maximal pain at onset and at present should be determined. The pain should be characterized as diffuse or localized. Time course of pain should be characterized as either constant, intermittent, decreasing, or increasing.
Acute exacerbation of longstanding pain suggests a complication of chronic disease such as peptic ulcer disease, inflammatory bowel disease, or cancer. Sudden, intense pain often represents an intraabdominal catastrophe
(eg, ruptured aneurysm, mesenteric infarction, or intestinal perforation). Colicky abdominal pain of intestinal or ureteral obstruction tends to have a gradual onset.
Intermittent pain is associated with spasmodic increases in pressure within hollow organs.
Bowel ischemia initially causes diffuse crampy pain due to spasmodic contractions of the bowel. The pain becomes constant and more intense with bowel necrosis, causing pain out of proportion to physical findings. A history of intestinal angina can be elicited in half of patients.
Constant pain. Biliary colic from cystic or common bile duct obstruction usually is constant. Chronic pancreatitis causes constant pain. Constant pain also suggests parietal peritoneal inflammation, mucosal inflammatory conditions, or neoplasms.
Appendicitis initially causes intermittent periumbilical pain. Gradually the pain becomes constant in the right lower quadrant as peritoneal inflammation develops.
Sciatica Treatment Exercises Guide and Image Sciatica differs from other types of back problems in the way the pain is felt. Sciatica pain can be a dull ache felt in the buttocks or a shooting pain that radiates down the leg. Sciatica symptoms can be numbness or 'pins and needles' and is commonly felt in the foot.
Sciatica back pain is located in the lower back but is usually less severe than other accompanying sciatica pain. There are several sciatica treatment options which can be used to give pain relief and can range from exercises to surgery.
Diverticulitis Diet Foods to Avoid A low residue diet is one that consists of a daily intake of no more than 10 grams of fiber. While on this diet for an extended period of time it is recommended that a multi-vitamin or mineral supplement be taken daily. This ensures that minerals and vitamins lost while on the low residue diet are made by taking supplements.
Until recently, many doctors suggested avoiding foods with small seeds because it was believed that particles could lodge in the diverticula and cause inflammation. However, this is now a controversial point and no evidence supports this recommendation. So the seeds in tomatoes, zucchini, cucumbers, strawberries and raspberries, as well as poppy seeds, which are part of your diverticulitis diet, are generally considered harmless.
Colon Rectum Cancer Symptoms and Therapy Cancer of the colon (large intestine) and rectum is the second leading cause of cancer-related deaths in the United States. Each year it claims an estimated 48,000 lives, and produces about 107,000 new cases—more than any other kind of cancer except skin cancer. It afflicts men and women about equally. The five-year survival rate from this form of cancer, usually after surgery, is about 90 percent where the cancer was localized about 65 percent where there was regional involvement. The death rate from colon and rectum cancer has decreased significantly over the past 20 years due to, among other factors, improved treatments and earlier diagnosis.
Leprosy Picture Symptoms and Treatment Cure What is Leprosy
Leprosy or Hansen's disease (HD), is a chronic disease caused by the bacteria Mycobacterium leprae and Mycobacterium lepromatosis. Named after physician Gerhard Armauer Hansen, leprosy is primarily a granulomatous disease of the peripheral nerves and mucosa of the upper respiratory tract; skin lesions are the primary external sign. Left untreated, leprosy can be progressive, causing permanent damage to the skin, nerves, limbs and eyes. Contrary to folklore, leprosy does not cause body parts to fall off, although they can become numb or diseased as a result of infection; infection results in tissue loss, so fingers and toes become shortened and deformed as the cartilage is absorbed into the body.
Currently, there are several areas (India, East Timor) of the world where the WHO and other agencies (for example, the Leprosy Mission) are working to decrease the number of clinical cases of leprosy and other diseases such as rabies and schistosomiasis that occur in remote regions. Although researchers hope to eliminate leprosy like smallpox, endemic (meaning prevalent or embedded in a region) leprosy makes complete eradication unlikely. In the U.S., leprosy has occurred infrequently but is considered endemic in Texas, Louisiana, Hawaii, and the U.S. Virgin Islands by some investigators.
Naproxen Side Effects 500mg Long Term Naproxen is in a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). It works by reducing hormones that cause inflammation and pain in the body.
Diabetes Mellitus Treatment Diabetes mellitus is a chronic disease which is difficult to cure. Management concentrates on keeping blood sugar levels as close to normal ("euglycemia") as possible without presenting undue patient danger. This can usually be with close dietary management, exercise, and use of appropriate medications (insulin only in the case of type 1 diabetes mellitus. Oral medications may be used in the case of type 2 diabetes, as well as insulin).
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.
