The spleen, thymus gland, tonsils, and lymph nodes are:
Concerned only with destroying RBCs
Confined to the thoracic cavity
Lymphoid organs
Concerned only with phagocytosis
The Correct Answer is C
A. Concerned only with destroying RBCs
Only the spleen is partly involved in RBC destruction-this doesn’t apply to all listed organs.
B. Confined to the thoracic cavity
These organs are located in different parts of the body-e.g., spleen in the abdomen, lymph nodes throughout the body.
C. Lymphoid organs
These are all components of the lymphatic/immune system, involved in immune surveillance and lymphocyte production.
D. Concerned only with phagocytosis
While some have phagocytic activity (e.g., macrophages in lymph nodes), their functions go far beyond phagocytosis (e.g., immune cell activation).

Correct Answer is B
Explanation
A. Spleen:
The spleen filters blood and helps initiate immune responses, but it does not mature T cells.
B. Thymus gland:
The thymus is the primary site where immature T lymphocytes mature and become functional.
C. Tonsils:
Tonsils help detect pathogens entering through the mouth or nose but are not involved in T cell maturation.
D. Pancreas:
The pancreas is involved in digestion and blood glucose regulation, not immune cell development.
