Platelet

Platelets are biconvex discs, fragments of cytoplasm 2–3 µm in diameter, found only in the blood of mammals. Platelets form by budding off from megakaryocytes in the bone marrow, and then entering the circulation. They help stop bleeding.On a stained blood smear, platelets appear as dark purple spots, about 20% the diameter of red blood cells. The smear is used to examine platelets for size, shape, qualitative number, and clumping. The main function of platelets is to contribute to hemostasis: the process of stopping bleeding at the site of interrupted endothelium. First, platelets stick to substances outside the interrupted endothelium: adhesion.
