Final answer:
The gland that stimulates the maturation of lymphocytes into T cells and coordinates immune defenses is the thymus gland. Thymocytes, which are immature T lymphocytes, are produced in the red bone marrow and then travel to the thymus for maturation.
Step-by-step explanation:
The gland you are stimulating the maturation of lymphocytes into T cells and coordinating immune defenses is the thymus gland.
Thymocytes, which are immature T lymphocytes, are produced in the red bone marrow and then travel to the thymus for maturation. Within the thymus, thymocytes undergo a series of steps to mature into functional T cells, which play a critical role in the cell-mediated immune response.
The thymus is a primary lymphoid organ involved in the development and maturation of T cells, and it is particularly active during infancy and childhood.
