Monocytes are the largest type of white blood cells (WBCs). They possess a large bean-shaped (kidney-shaped) nucleus and are highly phagocytic, meaning they engulf and destroy pathogens, dead cells, and foreign particles.
Key Features of Monocytes:
Largest WBCs
Bean/Kidney-shaped nucleus
Strong phagocytic activity
Differentiate into macrophages in tissues
Important component of innate immunity
Therefore, the correct answer is Monocytes.
