What type of blood cells are primarily and specifically responsible for specific immunity?
Correct answer: D. Lymphocytes
- A. Erythrocytes
- B. Thrombocytes
- C. Neutrophils
- D. Lymphocytes
Explanation
Lymphocytes, the B and T cells, recognise specific antigens and carry out specific immunity through antibodies and cell mediated responses. Neutrophils are phagocytes of the non specific defence, thrombocytes take part in clotting and erythrocytes carry oxygen.

About Specific Defense Mechanism
Specific defense mechanisms provide targeted immunity through B lymphocytes, T lymphocytes, antibodies and memory cells that recognize particular antigens. Questions cover humoral and cell mediated responses, clonal selection, primary and secondary immune responses, vaccination and passive immunity, while distinguishing adaptive defenses from the immediate, non specific innate response.
