macrophage
Type of white blood cell, or leucocyte, found in all vertebrate animals. Macrophages specialize in the removal of bacteria and other micro-organisms, or of cell debris after injury. Like phagocytes, they engulf foreign matter, but they are larger than phagocytes and have a longer lifespan. They are found throughout the body, but mainly in the lymph and connective tissues, and especially the lungs, where they ingest dust, fibres, and other inhaled particles.
