Which of these is a lymphoid organ?

• A. Tonsill
• B. Spleen
• C. Thymus
• D. All of these

Hint:

Lymphoid organs are critical to the immune system, and all three mentioned organs contribute significantly to immune function.

Answer 1

The Correct Option is D

Lymphoid organs are those organs that play a crucial role in the body's immune response. They are involved in the production and maturation of lymphocytes, which are white blood cells involved in the immune response. The main lymphoid organs are: - Tonsils: These are lymphoid tissues located at the back of the throat that help trap pathogens entering through the mouth and nose. - Spleen: This organ filters blood, removing old and damaged red blood cells and playing a key role in the immune response by helping the body fight infections. - Thymus: The thymus is responsible for the maturation of T lymphocytes (T cells), which are critical for adaptive immunity. Since all three organs are involved in immune functions and lymphocyte production or maturation, the correct answer is (d) All of these.
