Question

Bone marrow : Production of lymphocytes :: _________ : Maturation of T lymphocytes

• A. Thymus
• B. Adrenal
• C. Appendix
• D. Lymph nodes

Answer 1

The correct option is A Thymus

Bone marrow and thymus are primary lymphoid organs. Bone marrow produces B - cells and T - cells,
B - cells attain maturity in bone marrow whereas T - cells differentiate into antigen sensitive lymphocytes in thymus.

Adrenal gland produces hormones like adrenaline and is found on the top of the kidneys.
Appendix acts as a secondary lymphoid organ during early years of development.

Lymph nodes are small structures found at different locations in the lymphatic system, which serve to trap the antigens if they enter the lymph.
