Question

Which WBC plays significant role in allergic reaction?

• A. Monocytes
• B. Basophils
• C. Lymphocytes
• D. Erythrocytes

Answer 1

The correct option is B Basophils

A. Monocytes are agranular WBCs which are actively motile and phagocytic cells.

B. Basophils are granular WBCs which release histamine, serotonin and heparin. Histamine induces allergic symptoms in response to allergens (allergy causing substances) in the body.

C. Lymphocytes are agranular WBCs which produce antibodies and play an important role in immunity.

D. Erythrocytes or red blood cells transport oxygen in body tissues.

So, the correct answer is 'Basophils'.
