Introduction: Platelets

Platelets help the blood clot by clumping together into larger clots. This helps to prevent and stop bleeding from internal or external wounds.

Article Excerpts about Platelets

Platelets (also called thrombocytes ) help form blood clots that control bleeding. (Source: excerpt from What You Need To Know About Leukemia: NCI)

Summary Information: Platelets

Platelets: Platelets are one cellular component of blood. Platelets are actually oval shaped bits of broken-up cells called megakaryocytes. Platelets play a vital role in blood clotting and the prevention of excessive blood loss.

Platelets are important to the process of chemical clotting, in which the platelets react with a variety of chemicals in the body, called clotting factors, to form a fibrin clot. Platelets also work in other ways to stop or minimize bleeding. In response to bleeding from a large blood vessel, platelets release a chemical that stimulates vasoconstriction, which narrows the blood vessel. This not only allows less blood to bleed out from the vessel, but enables a clot to lodge in the narrowed vessel to obstruct the bleeding. When small capillaries are cut or are ruptured, platelets also create a platelet plug to stop the bleeding.

Conditions that can afflict the platelets include thrombocytopenia, thrombocytosis, and chemotherapy.
