What is a platelet?

platelet is a piece of larger cell called megakaryocyte. Tromboyctes, also called plates, are found in the blood. In general, its main purpose is to help with a clot if necessary, for example, when cutting in the skin. There are several types of platelet disorders that can affect the ability of blood if necessary to precipitate. When more platelets are needed in the body, the liver produces a hormone called thrombopetin, which stimulates bone marrow to produce more megocaryocytes, which can then be divided into hundreds of smaller pieces of platelets. In general, platelets last only in the body of about seven to ten days, when it is usually destroyed by the spleen.

One of the primary roles of thrombocytes is to help a blood clot. Thrombocytes are suitable for this function well, because these usually have sticky proteins on the outer surfaces and the ability to drag and change the shape. This means that when it comes into contact with broken blood vessels, sticky proteins can usually be attached to cells in broken vessel walls and to others tRombocytes. Together, these platelets usually bend and stretch and create a plug into a broken container. This process can occur both inside the body, such as stopping internal bleeding and outside the body, such as stopping bleeding from the cut.

There are several types of thrombocyte disorders that can affect blood ability to create clots. These disorders generally fall into three main categories: to have too little or too much platelets or have platelets that do not work as they should. Low platelet levels, also called thrombocytopenia, may be caused by problems such as the abnormal reaction of the immune system, the drug transfusion or the side effect of a particular medidacation. The high levels of platelets, also called thrombocythemia, may be caused by problems, such as a change in the way the stem cells in the bone marrow work. The presence of platelets in the body that does not work properlythat be caused by genetic disorders such as von Willibrand's disease or certain drugs such as aspirin.

In general, regardless of what the cause or type of platelet disorder is, many of the same symptoms can be observed due to similar changes in blood clotting of disorders. Such symptoms may include, for example, large bruises caused by minor injuries, cutting from cuts that do not stop and bleed from fine body tissues such as gums. Serious problems caused by platelet disorders can also be similar and include potentially fatal blood loss and brain bleeding.
