Phagocytosis is the process by which a cell engulfs solid material. The molecule is then internalized in a vesicle of plasma membrane (phagosome) which fuses with a lysosome for destruction, any undigested remains of the molecule (eg. bacterium) are removed by exocytosis and the products of digestion are absorbed into the cytoplasm. It occurs in the immune system, and is carried out by phagocytes such as macrophages which are involved in the innate immune response [1].
