Phlebotomies
Phlebotomy is the process of making a puncture in a vein, usually in the arm, with a cannula for the purpose of drawing blood. The procedure itself is known as a venipuncture, which is also used for intravenous therapy. A person who performs a phlebotomy is called a ''phlebotomist'', although most doctors, nurses, and other technicians can also carry out a phlebotomy. In contrast, phlebectomy is the removal of a vein. Phlebotomies that are carried out in the treatment of some blood disorders are known as '' therapeutic phlebotomies''. The average volume of whole blood drawn in a therapeutic phlebotomy to an adult is 1 unit (450-500 ml) weekly to once every several months, as needed. Etymology From grc, φλεβοτομία ( – 'blood vessel, vein' + 'cutting'), via fro, flebothomie (modern French ). Phlebotomies Phlebotomies are carried out by phlebotomists – people trained to draw blood mostly from veins for clinical or medical testing, transfusions, donations, or rese ...

Iron Overload
Iron overload or hemochromatosis (also spelled ''haemochromatosis'' in British English) indicates increased total accumulation of iron in the body from any cause and resulting organ damage. The most important causes are hereditary haemochromatosis (HH or HHC), a genetic disorder, and transfusional iron overload, which can result from repeated blood transfusions. Signs and symptoms Organs most commonly affected by hemochromatosis include the liver, heart, and endocrine glands. Hemochromatosis may present with the following clinical syndromes: * liver: chronic liver disease and cirrhosis of the liver. * heart: heart failure, cardiac arrhythmia. * hormones: diabetes (see below) and hypogonadism (insufficiency of the sex hormone producing glands) which leads to low sex drive and/or loss of fertility in men and loss of menstrual cycle in women. * metabolism: diabetes in people with iron overload occurs as a result of selective iron deposition in islet beta cells in the pancreas lead ...

Vein
Veins are blood vessels in humans and most other animals that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart. Veins are less muscular than arteries and are often closer to the skin. There are valves (called ''pocket valves'') in most veins to prevent backflow. Structure Veins are present throughout the body as tubes that carry blood back to the heart. Veins are classified in a number of ways, including superficial vs. deep, pulmonary vs. systemic, and large vs. small. * Superficial veins are those closer to the surface of the body, and have no corresponding arteries. *Deep veins are deeper in the body and have corresponding arteries. *Perforator veins drain from the superficial to the deep veins. These are usually referred to in the lower limbs and feet. *Communic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
