How does a white blood cell ingest and kill a bacteria?

White blood cells can kill pathogens in multiple ways, one of these is called phagocytosis. During phagocytosis, a specific white blood cell called a phagocyte recognises the bacteria through a process called chemoattraction. This allows the phagocyte to move towards the bacteria by detecting chemicals released. The phagocyte then engulfs the bacteria, after binding to the membrane. Once the bacteria has been engulfed it is inside a membane in the cell (a phagocytic vacuole). A lysosome then fuses with the phagocytic vacuole to release enzymes with digest the bacteria. These enzymes are called lysozymes. After destroying the engulfed baceria, antigens from the pathogen are moved to the outside of the cell membrane, allowing the phagocyte to become an antigen presenting cell which activates further activation of the immune response to the bacteria.
