hormone that stimulates the development of the immune system and the production of lymphocytes
The gland produces thymosins, which are hormones that stimulate the development of antibodies. The thymus also produces T-lymphocytes which are white blood cells that fight infections and destroy abnormal cells. The thymus gland is very active in childhood.It plays a crucial role in developing and improving a child's immune system.fter the white blood cells mature, they leave the thymus gland and get settled in the spleen and the lymph nodes, where a fresh batch of T cells is produced. These white blood cells are the body's immune system and protect the body by producing antibodies that stop the invasion of foreign agents, bacteria and viruses.
