phag·o·cyte

(fag'ō-sīt),
A cell that can ingest bacteria, foreign particles, and other cells. Phagocytes ingest and kill microbes, present antigen to lymphocytes, scavenge degenerating material, and release mediators. classes: 1) microphages, polymorphonuclear leukocytes that ingest chiefly bacteria; 2) macrophages, mononucleated cells (histiocytes and monocytes) that are largely scavengers, ingesting dead tissue and degenerated cells.
