White Blood Cells: Soldiers Of The Body

The White blood cells (Leukocytes), are known as the soldiers of the body, this is because these are the blood cells that help fight infection with their phagocytic action. There are about eight thousand of these per cubic millimetre. There are several types of these throughout the body.
Granulocytes are an example, these are able to fight infection by squeezing through the capillary wall. The other leukocyte is called lymphocyte and is found in the blood, spleen and lymph nodes. All these play a part in the formation of
antibodies.
