Macrophages are a type of monocyte that matures in the tissues and in the different tissues they are called by different names: in the alveoli of the lungs, they are called alveolar macrophages; in the tissues they are called histiocytes; in the liver they are called Kupffer cells; in the bones they are called osteoclasts; and in the peritoneum they are called peritoneal macrophages.[1] Their major role is to phagocytose invaders, especially bacteria. They also serve as antigen-presenting cells, although less so than do dendritic cells.[2]
