The Thymus Gland
LocationUpper chest underneath the breastbone
Directly under the sternum
Divided into two lobes– left and right– on the front of the trachea
Shrinks as humans become older
Hormone ProductionThymosin – changes lymphocytes into T-cells
Thymopoietin – relatively unknown purpose
Humoral Factor – creates B-cells
Thymic Factor – divides the T-cells into different areas of identification
ImportanceCreates the immune system and helps prevent disease and infection
Maintains homeostasis by keeping out foreign invaders
Without the Thymus, humans would easily die from disease
Feedback Mechanisms
The Thymus gland does not have any antagonistic hormones
The Thymus gland has little to feedback mechanisms either because they do not exist or not enough is known about the gland.
Early growth 1 stops cells from entering the Thymus in early childhood
Thymus MalfunctionLowered production of T-cells
Higher susceptibility to disease and infection
Increased chance to gain an autoimmune disorder such as HIV/AIDS, as well as cancer, and most commonly DiGeorge syndrome
Can be treated by surgically removing the Thymus, a Thymus transplant, and chemotherapy
