- Phagocytes are white blood cells which engluf foreign matter.
- Neutrophils & macrophages are types of phagocytes.
- Chemical released by the bacteria attract phagocytes to the site.
- Once the neutrophils or macrophages reach the site they engulf the foreign matter which has antigens on the surface.
- Once the forgein matter has been engulfed the material is enclosed within a vacoule.
- The vacoule then fuses with the lysosomes which contain enzymes.
- The lysosome then release the enzymes and destroy the foreign material.
