Granulocyte
mature white blood cells with granules in the cytoplasm / From Wikipedia, the free encyclopedia
Granulocytes are a category of white blood cells which have granules in their cytoplasm.[1] They are also called polymorphonuclear leukocytes because of the shape of the nucleus, which has three segments. The term polymorphonuclear leukocyte often refers just to neutrophils, the most abundant of the granulocytes.
Granulocytes are released from the bone marrow. They operate by phagocytosis and other means.[2]
