Question

Find out the primary lymphoid organ from the following:

• A. Spleen
• B. Lymph nodes
• C. Thymus gland
• D. Tonsils

Hint:

Primary lymphoid organs such as the thymus and bone marrow are responsible for the production and maturation of immune cells, while secondary lymphoid organs like the spleen and lymph nodes are involved in immune responses.

Answer 1

The Correct Option is C

The thymus gland is the primary lymphoid organ where T-lymphocytes (T-cells) mature and differentiate. It plays a critical role in the immune system, unlike the spleen, lymph nodes, and tonsils, which are secondary lymphoid organs involved in filtering lymph and providing immune responses.
