Explanation:
Phagocytes use phagocytosis as a mechanism to eliminate large pathogens (mostly bacteria). They do this by expanding their plasma membrane around the pathogen. As a consequence, the pathogen is enveloped in a vesicle and incorporated inside the cell. Once inside, the lysosomes are incorporated, providing enzymes capable of destroying the microbe.
