What is the role of the thymus in the immune system?

The thymus is a primary lymphoid organ essential for the development of T lymphocytes, which orchestrate adaptive immune responses. ... Thymic output is also temporally regulated due to age-related involution of the thymus accompanied by loss of epithelial cells.

How does the spleen work in the immune system?

The spleen plays multiple supporting roles in the body. It acts as a filter for blood as part of the immune system. Old red blood cells are recycled in the spleen, and platelets and white blood cells are stored there. The spleen also helps fight certain kinds of bacteria that cause pneumonia and meningitis.

How does thymus gland play a major role in the development of immunity?
