Quizplus · Accepted Answer

The process described involves the white blood cell engulfing or "eating" the bacterium, which is known as phagocytosis. Osmosis is the movement of water molecules across a membrane, receptor-mediated endocytosis involves specific molecules being selectively taken into the cell, and exocytosis is the process of releasing molecules from the cell.
