White Blood Cells Engulf Bacteria Through What Process

Question

White blood cells engulf bacteria through what process?
A)exocytosis
B)phagocytosis
C)pinocytosis
D)osmosis
E)receptor-mediated exocytosis

Accepted Answer

White blood cells engulf bacteria through phagocytosis, which is a process of engulfing and internalizing solid particles or microorganisms. During phagocytosis, the white blood cell surrounds the bacteria with its cell membrane, creating a pocket called a phagosome. The phagosome then fuses with a lysosome containing digestive enzymes, forming a phagolysosome where the bacteria are destroyed.
