Macrophage. Coloured scanning electron micrograph (SEM) of a macrophage white blood cell. Macrophages are cells of the body's immune system. They are found in the tissues rather than in the circulating blood. Macrophages recognise foreign particles, including bacteria, pollen and dust, and phagocytose (engulf) and digest them.
