Question

The most active phagocytic white blood cells are

• A. Eosinophils and lymphocytes
• B. Neutrophils and monocytes
• C. Neutrophils and eosinophils
• D. Lymphocytes and macrophages

Answer 1

The correct option is B Neutrophils and monocytes

Eosinophils are a type of WBCs. They are granulocytes and are involved in combating infections by releasing granular proteins or by degranulation.
Lymphocytes are B-cells or T-cells and they have receptors on their surface and are able to bind antigens and thus, help the foreign substance to get removed from the body.
Neutrophils are the most abundant type of WBCs. They are phagocytic in nature and are able to engulf foreign substances (like bacteria).
Monocytes are a type of WBCs. Monocytes mature in different types of macrophages at different locations. Monocytes and their macrophages serve three main functions as phagocytosis, antigen presentation and cytokine production.
Thus, the correct answer is option B.
