How could a bacterial cell enter a white blood cell in order to be digested?

A bacterial cell can enter a white blood cell through a process called phagocytosis. In this process, the white blood cell recognizes the bacteria as foreign and extends its cell membrane around it, engulfing the bacterium. Once inside, the bacterium is enclosed in a vesicle called a phagosome, which then fuses with lysosomes containing digestive enzymes that break down the bacterial cell. This mechanism allows the immune system to eliminate pathogens effectively.
