Macrophage. Transmission electron micrograph (TEM) of a macrophage cell. The cell's nucleus is at centre right. Mitochondria (oval) in the cell's cytoplasm produce energy for the cell. Lysosomes (large, dark grey) contain enzymes for digesting foreign particles. Macrophages are a type of large white blood cell that are found in tissues rather than circulating in the blood. They recognise foreign particles, including bacteria, pollen and dust, and phagocytose (engulf) and digest them. Magnification: x5000 when printed 10 centimetres wide | |
