Blood cell

Blood cell refers to any type of cell normally found in blood. In mammals, these fall into three general categories:

white blood cells, which act as immune cells and fight infection
Platelets, which are actually fragments of the large bone marrow cells known as megakaryocytes[?] and are important in blood clotting
