During an immune response, what type of cells are PRIMARILY involved in the production of antibodies?
Correct answer: B. B lymphocytes
- A. T lymphocytes
- B. B lymphocytes
- C. Macrophages
- D. Platelets
Explanation
B lymphocytes, once activated, become plasma cells that produce antibodies, which makes them responsible for humoral immunity. T lymphocytes carry out cell mediated immunity and help B cells, macrophages engulf antigens and platelets take part in clotting.

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.
