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.
There are five different types of white blood cells, also called leukocytes, found in the human bodies. White blood cells all help to defend the body from foreign particles in some way.All white blood cells are produced in red bone marrow, with the special type lymphocytes also being formed in lymphatic tissue.ogether all these types of white blood cells coordinate a system that defends the body from infection, damage and even cancer. Neutrophils are the most numerous of the white blood cells. They are often called bacterial slayers because they're usually function is killing foreign bacteria in the body.
