Blood cell
From Wacklepedia - 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 cells, whose main purpose is the transport of oxygen
- 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
