ThymusFor a long time scientists knew little about the thymus gland, but now it is now known to be a central to the body's defense mechanisms. The thymus gland is located in the chest near the heart. Lymphocytes a type of white blood cell mature in the thymus before coming fully able to help rid the body of infectious agents such as versus. Lymphocytes are sent to the spleen and lymph where they further develop and mature. The development of our bodies to resist infection of all kinds depends upon seeding and proliferation of these lymphocytes. The thymic hormone stimulates the spleen and lymph nodes to produce lymphocytes from their own plasma cells. Even before birth, the thymus sends out colonists or migrating lymphocytes to establish new footholds in the spleen and lymph nodes. Then the thymus continues to supply these colonists by sending a continued supply or powerful lymphatic hormones. The knowledge about the thymus has also raised hopes for more effective management of such auto-immune conditions. Experimental evidence suggest that the production of these antibodies may be the result of thymic function. The thymus produces a number of hormone-like substances, such as thymusin, which appears to stimulate this process. In later life the thymus shrinks progressively with increasing age. This restless increase in size may be one of the reasons that infections are common in older people. Abnormalities of the thymus indicate the importance of its normal activity. According to research the use of raw thymus tissue may strengthen and support the immune system. These statements have not been evaluated by the Food And Drug Administration.
