Also known as thrombocyte W, thrombocytes, blood platelet, blood platelets, platelets
Platelets or thrombocytes () are a part of blood whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping to form a blood clot. Platelets have no cell nucleus; they are fragments of cytoplasm from megakaryocytes which reside in bone marrow or lung tissue, and then enter the circulation. Platelets are found only in mammals, whereas in other vertebrates (e.g. birds, amphibians), thrombocytes circulate as intact mononuclear cells.
AI overview
Platelets are tiny fragments in your blood that work together with other clotting factors to stop bleeding by forming clots when blood vessels are injured. These cell fragments come from larger cells in your bone marrow and lungs, and unlike thrombocytes in other animals, mammalian platelets lack a nucleus.
