GENERAL HISTOLOGY

Detailed explanation-1: -THE THYMUS IS A PRIMARY LYMPHOID ORGAN ESSENTIAL FOR THE DEVELOPMENT OF T LYMPHOCYTES WHICH ORCHESTRATE ADAPTIVE IMMUNE RESPONSES.

Detailed explanation-2: -T cells (also called T lymphocytes) are major components of the adaptive immune system. Their roles include directly killing infected host cells, activating other immune cells, producing cytokines and regulating the immune response.

Detailed explanation-3: -The thymus produces and secretes thymosin, a hormone necessary for T cell development and production. The thymus is special in that, unlike most organs, it is at its largest in children. Once you reach puberty, the thymus starts to slowly shrink and become replaced by fat.
