Which human blood cells are responsible for phagocytosis and act as primary phagocytic cells of the innate immune system?

A. Erythrocytes
B. Neutrophils and Monocytes✓ Correct Answer
C. Thrombocytes
D. B-lymphocytes

💡 Solution & Explanation

Neutrophils and monocytes act as the primary professional phagocytes of the innate immune system, actively migrating toward infection sites to engulf, digest, and destroy foreign pathogens through phagocytosis. Erythrocytes, or red blood cells, are specialized exclusively for oxygen transport across the body, while thrombocytes, or platelets, are vital for blood clotting. B-lymphocytes belong to the adaptive immune system and function primarily by producing specific antibodies rather than direct cellular phagocytosis.
