Phagocyte - Wikipedia
WEBPhagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells. Their name comes from the Greek phagein, "to eat" or "devour", and "-cyte", the suffix in biology denoting "cell", from the Greek kutos, "hollow vessel". [1] .

WEBPhagocyte, type of cell that has the ability to ingest, and sometimes digest, foreign particles, such as bacteria, carbon, dust, or dye. It engulfs foreign bodies by extending its cytoplasm into pseudopods (cytoplasmic extensions like feet), surrounding the foreign particle and forming a vacuole.
