White blood cells that have the job of protecting the body from infection by getting around bacteria and eating it (phagocytosis)
Blood platelets that are necessary for blood to clot (or stop flowing) to prevent bleeding to death
The liquid portion of the blood that carries the blood cells
Stem cell
A special cell found in the bone marrow that all cells begin from.
The process of making red blood cells or erythrocytes. It is released into the body when more red blood cells are needed. During exercise, rise in temperature

Agranulocytes are also white blood cells
(Lympocytes (synthesis of antibodies)
Monocytes-form macrophages for phagocytosis
