  2. Thymus Gland Definition The thymus gland is a secretory gland that has an important role in immune function. One of its main secretions is the hormone thymosin. Thymosin stimulates the maturation of T cells, which are derivatives of white blood cells that circulate our system
  3. The thymus gland is the main organ of the lymphatic system. Located in the upper chest, this gland's primary function is to promote the development of cells of the immune system called T lymphocytes. T lymphocytes, or T-cells, are white blood cells that protect against foreign organisms (bacteria and viruses) that manage to infect body cells

  4. Thymus gland structure and function. The thymus has two lobes and each lobe is divided into a central medulla and a peripheral cortex. The thymus is a crucial component that is responsible for maintaining proper immune system function in the body and especially active in young children. The thymus secretes hormones that regulate the immune system
  5. The thymus is a largely neglected organ but plays a significant role in the regulation of adaptive immune responses. The effect of aging on the thymus and immune senescence is well established, and the resulting inflammaging is found to be implicated in the development of many chronic diseases inclu

Thymus Gland - Definition, Function and Location Biology

Thymus, pyramid-shaped lymphoid organ that, in humans, is immediately beneath the breastbone at the level of the heart.The organ is called thymus because its shape resembles that of a thyme leaf.
