Thymus Gland


The pinkish-grey coloured gland located at the upper part of the chest is the thymus gland. It is one of the main organs of the immune system. At birth, this gland is quite small but as growth progresses its size increases. It grows till a person attains puberty and then it shrinks again. Its functions are not much explored, but studies suggest that the thymus gland promotes the development of specific cells of the immune system called T-lymphocytes that protect the body against bacteria and viruses. It also accelerates metabolism and speeds up growth.
