Describe how phagocytic white blood cells destroy bacteria. (4)

The phagocyte recognises antigens on the surface of the bacteria as foreign, causing it to be attracted to the bacteria. The phagocyte then engulfs the bacteria, forming a vesicle around it. Lysozomes fuse with the vesicle and release digestive enzymes into it which hydrolyses the bacteria.
