Macrophage. Coloured transmission electron micrograph (TEM) of a macrophage cell. The cell's nucleus is bright green. Mitochondria (green) in the cell's cytoplasm produce energy for the cell. Lysosomes (red) 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 | |
