Macrophage and bacteria. Computer artwork of a macrophage white blood cell (purple) phagocytosing (engulfing) a bacterium (red). Macrophages are immune system cells that phagocytose and destroy pathogens, dead cells and cellular debris. After phagocytosis they display fragments of a pathogen's proteins on surface receptors to direct other cells to attack the pathogen.
