How many platelets are in thrombocytopenia?
Thrombocytopenia means you have fewer than 150,000 platelets per microliter of circulating blood. Because each platelet lives only about 10 days, your body normally renews your platelet supply continually by producing new platelets in your bone marrow.
Why do platelets stop bleeding?

Considered platelets one of the components of blood, characterized these cells as being free of nuclei and the color of her, and in fact consists of platelets in the bone marrow, and once ripe , they turn to blood, and from there move to the spleen is stored and released when the body 's need This occurs when one of the vascular vessels is damaged or ruptured, which causes bleeding, and as soon as the platelets reach the site of the bleeding, they collect and accumulate to form a surface that hears the clotting factors gathering on it, so that the body has succeeded in trying to stop the bleeding.
What is the condition where blood clots are scattered in parts of the body?
Thrombotic thrombocytopenic purpura: This condition is represented by the formation of blood clots scattered in parts of the body for reasons of unknown cause, and that these clots require the collection of large numbers of platelets and this explains the decrease in their number in such cases, and can be It should be noted that this case is rare.
