Thymus. The thymus gland is the main organ of the lymphatic system. Located in the upper chest region, the primary function of this gland is to promote the development of specific cells of the immune system called T lymphocytes.nce mature, these cells leave the thymus and are transported via blood vessels to the lymph nodes and spleen. T lymphocytes are responsible for cell mediated immunity, which is an immune response that involves the activation of certain immune cells to fight infection.
The thymus gland also produces a hormone called thymosin, which stimulates the T cells in the other lymphatic organs to mature. This gland also produces another hormone called thymopoietin, which is protein present in the mRNA (messenger RNA) and is encoded by the TMPO gene.nother function of thymus gland is to prevent the abnormal growth of cells, that may lead to cancer. The T lymphocytes travel from the bone marrow to the thymus gland where they remain until they get activated. After maturity, the lymphocytes enter the blood stream.
