Explanation:
Detailed explanation-1: -Thymus. The thymus is an immune organ controlling the development of lymphocytes. It also produces thymopoietins and thymosins, which are hormones important to the immune system (Wilson, 2009).
Detailed explanation-2: -Immunoincompetent T cell precursors from the bone marrow enter the cortex of the thymus to proliferate and become immunocompetent T cells. To do this, they must contact various epithelial reticular cells of the cortex and develop some and eliminate other surface markers.
