What is the name of the process by which white blood cells engulf and digest harmful pathogens and cellular debris?
A. Pinocytosis
B. Phagocytosis✓ Correct Answer
C. Exocytosis
D. Osmosis
💡 Solution & Explanation
Phagocytosis is the cellular mechanism by which specialized white blood cells such as macrophages and neutrophils engulf and digest large foreign particles, bacteria, and cellular debris. Pinocytosis refers to the ingestion of surrounding fluid and dissolved solutes by small vesicles, representing cellular drinking rather than solid particle engulfment. Understanding cellular defense mechanisms is fundamental for questions related to human immunology and physiology.
