Final answer:
Phagocytized particles undergo enzymatic digestion following the fusion of the phagosome with a lysosome.
Step-by-step explanation:
Phagocytosis is the process by which phagocytes, such as white blood cells, engulf and digest pathogenic particles. The phagocytized particles undergo enzymatic digestion following the fusion of the phagosome, an intracellular vesicle, with a lysosome. Once fused, the lysosome's hydrolytic enzymes break down and destroy the pathogen in the phagolysosome.
