- A phagocyte (e.g a macrophage) is a type of white blood cell that carried out phagocytosis. They are found in the blood and in tissues and are the first cells to respond to a pathogen`
1) Phagocyte recognises antigens on pathogen
2) Cytoplasm of phagocyte engulfs pathogen
3) Pathogen is contained in a phagocytic vacuole in the cytoplasm of the phagocyte
4) Lysosome fuses with phagocytic vacuole breaking down the pathogen
5) Phagocyte presents the pathogen's antigens on its surface to activate other immune system cells
