The central function of vacuoles in multicellular animal cells is in endocytosis and exocytosis. Prominent examples of vacuoles include the phagocytic vacuoles formed by the ingestion of a bacterium by macrophages in the immune system or the vacuoles formed in capillary cells carrying out pinocytosis and reverse pinocytosis in transporting serum from the blood to surrounding tissue space.
