Describe how a phagocyte defends the body
The phagocyte is attracted to a pathogen, the pathogen binds to the phagocyte and then the phagocyte engulfs the pathogen. The pathogen is then contained in a phagosome which has been cleaved off the membrane. The phagosome then combines with a lysosome containing hydrolytic enzymes, becoming a phagolysosome. The phagocyte is then broken down by the enzymes within the vesicle and the antigens from the pathogen are displayed on the surface of the phagocyte.
