Platelets, or thrombocytes, are small, disc-shaped cell fragments in the blood that play a crucial role in hemostasis, the process of blood clotting. They are produced in the bone marrow from large cells called megakaryocytes and help prevent bleeding by adhering to damaged blood vessels and aggregating to form clots. Additionally, platelets release chemical signals that promote further clotting and tissue repair. A normal platelet count is essential for maintaining proper blood coagulation and preventing excessive bleeding or clotting disorders.
