A number of different types of cells that are involved in phagocytosis; include neutrophils, monocytes, and tissue macrophages.
Phagocytes including granulocytes, monocytes (white blood cells) and specialized tissue cells (macrophages) are major cellular components of the non-specific immune system.
Cells that readily eat (ingest) microorganisms like bacteria or fungi and can kill them as a means of protecting the body against infection. The two principal phagocytes are neutrophils and monocytes. They emigrate out of the blood and into tissues in which an infection has developed. A severe decrease in the blood level of these cells is the principal cause of susceptibility to infection in patients treated with intensive radiotherapy and/or chemotherapy. The latter treatments suppress blood cell production in the marrow resulting in deficiencies of these phagocytic cells.
