Question

Quizplus · Accepted Answer

Phagocytosis is the process in which a white blood cell engulfs a bacterium and removes it from the bloodstream. Osmosis is the movement of water across a semipermeable membrane, diffusion is the movement of particles from an area of high concentration to an area of low concentration, and exocytosis is the process in which a cell expels waste products or other substances. None of these processes accurately describe the engulfment of a bacterium by a white blood cell.
