  • Phagocytosis
    • chemical products of the pathogen act as attractants, causing the phagocytes to move towards the pathogen
      • Phagocytes attach themselves to the surface of the pathogen
        • They engulf the pathogen to form a vesicle known as a phagosome
          • Lysosomes move towards the vesicle and fuse with it
            • Enzymes within the lysosomes break down the pathogen. The process is the same as that for the digestion of food in the intestines, namely the hydrolysis of larger, insoluble molecules into smaller, soluble ones
              • The soluble products from the breakdown of the pathogen are absorbed into the cytoplasm of the phagocyte
