WebbPlatelets, or thrombocytes, are tiny blood cells that bud from cells in the bone marrow (megakaryocytes). Platelets form clots when there’s damage to a blood vessel. For example, if you cut your finger, platelets mix with clotting factors (proteins in the blood). Together, they form a “glue” that stops the bleeding.
Platelets have no cell nucleus; they are fragments of cytoplasm that are derived from the megakaryocytes [2] of the bone marrow or lung, [3] which then enter the circulation.
