Engulfs pathogen in the membrane sac

The rise in body temperature reduces the rate of multiplication of pathogens. Increases the effect of phagocytosis.

Lysosome combines with membrane sac.

The presence of toxins produced by the pathogens\ stimulates the white blood cells.

The pathogens are degenerated and destroyed by the enzymes in lysosome
