How does phagocytes protect the body against pathogens?

Phagocytes protect the body against pathogens by identifying, engulfing, and digesting harmful microorganisms and debris through a process called phagocytosis. Once they recognize a pathogen, they extend their membrane around it, forming a phagosome that fuses with lysosomes to break down the invader using enzymes. Additionally, phagocytes can release signaling molecules that activate other immune cells, enhancing the overall immune response. This action helps to clear infections and maintain tissue health.
