Phagocytes of humans and other animals are called professional or non-professional, depending on how good they are at phagocytosis. The professional phagocytes are neutrophils, monocytes, macrophages, dendritic cells, and mast cells.
Neutrophils and monocytes are considered so-called professional phagocytes. Both arise from the same type of stem cell in the bone marrow. Monocytes normally represent roughly 1 to 10 percent of the circulating WBC population. Like neutrophils, these white blood cells can respond to a site of infection, activate and phagocytize invading bacteria. Monocytes also migrate into the body tissues, where they grow and transform into cells called macrophages.
