Granulocytes. The leukocytes, or white blood cells, defend the body against infecting organisms and foreign agents, both in the tissues and in the bloodstream itself (see immunity).Human blood contains about 5,000 to 10,000 leukocytes per cubic millimeter; the number increases in the presence of infection.his overproduction suppresses the production of normal blood cells. Conversely, a sharp decrease in the number of leukocytes (leukopenia) strips the blood of its defense against infection and is an equally serious condition.
Platelets. 1  These are small fragments of cells. 2  They developed from megakaryocytes. 3  They help the blood to clot when there is an injury, by adhering to the lining of the injured blood vessel.hite Blood Cells. White blood cells (WBC) also called leukocytes are the bodyâs defense cells. They protect our body from infections. They are much less than RBC but are very important in protecting the body. The Different Types of WBCs. There are various types of WBCs which have their own role in protecting the body.
