Alveolar macrophage. Coloured scanning electron micrograph (SEM) of an alveolar macrophage white blood cell from lung tissue. Macrophages are cells of the body's immune system that are found in the tissues rather than in the circulating blood. They recognise foreign particles,including bacteria,pollen and dust,and phagocytose (engulf) and digest them. Alveolar macrophages are associated with lung alveoli (air sacs) and epithelium (lining tissue). Their role is primarily to remove dust,hence their other name of dust cell | |
