Platelets are a component of blood that forms the clots as a dynamic process to stop hemorrhage. Platelets are formed by nuclei that are present in the bone marrow. Platelets are not cells, but are parts of an oblong form of the cytoplasm, The sheets are irregularly shaped, have no nerves or nuclei, and are seven to ten years old. Blood platelets dynamically work on coagulation, a search that has adhesion and differentiation ability, and signals Urges them to coagulation, which is more It is worth mentioning that platelets break down and disintegrate when they are touched by air in the blood clot. This is due to the damage caused by bleeding. Blood platelets move easily and slide regularly in the blood. , Because blood flow is stable, and platelets exist in the natural person by a quarter of a million, and the role of platelets essential in the transformation of protein substances of liquid nature formed in the blood, which is called the phyronogens, to a more solid substance, Are hardened threads All about the skin directly on the surface, and its role lies in preventing the leakage of blood from the skin.
It is noticeable that the platelets do not clot inside the blood vessels, because the blood flows naturally, and the liver works on the secretion of a substance known as Heparin limit the nature of platelet work, it is worth mentioning that platelets, after ten days, break the liver and spleen So as to be able to regenerate and differentiate, and can also be defined as objects of non-cellular nature, because they are not even break even.
Symptoms that may damage the human body due to lack of platelets, clotting occurs at the wound, causing bleeding lasting longer, and loss of a large amount of blood no matter how large the wound.
It is possible to transfer platelets from one person to another, so you can donate platelets from one person to another, using a medical device dedicated to draw blood and separation of platelets, and then return blood to the donor, it is worth mentioning that the natural person is able to donate a quantity ranging from 200-400 is taken at a rate of one time. The platelet donation takes about one hour. The person can make up the platelet count after 8 to 10 days, and the person can donate again after two weeks of donating for the first time.
