Blood cell
From Wikipedia, the free encyclopedia
A blood cell is any cell of any type normally found in blood. In mammals, these fall into three general categories:
- Red blood cell, whose main purpose is the transport of oxygen;
- White blood cell, which produces antibodies to fight infection;
- Platelet, which is actually a fragment of the large bone marrow cells known as megakaryocytes and are important in blood clotting.
