Many fast food chains design marketing promotions around popular sports and media events, and publicize contests as another way to get diners through their doors. References CBS News; Americans Are Obsessed with Fast Food: The Dark Side of the All-American Meal; Eric Schlosser; January 2001
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.
White blood cells are blood components that protect the body from infectious agents. Also called leukocytes, white blood cells play an important role in the immune system by identifying, destroying, and removing pathogens, damaged cells, cancerous cells, and foreign matter from the body. Leukocytes originate from bone marrow stem cells and circulate in blood and lymph fluid.
