Normal development of the immune response is due in part to hormones produced by the___
A) Thyroid gland
B) Adrenal medulla
C) Thymus Gland
C) Normal development of the immune response is due in part to the hormones produced by the thymus gland.
Note: The thymus is a small gland situated in the chest cavity just behind the upper end of the sternum or breastbone. The thymus gland processes many of the white blood cells that are produced in the bone marrow and converts these cells into T-lymphocytes.These cells have a crucial role in defending the body against infection. They stimulate the production of antibodies by other
lymphocytes and they also stimulate the growth and activity of the
phagocytes, which are a form of scavenger cell that ingest invading viruses and bacteria. The thymus gland is at its largest size in the
young infant and over the years it regresses in size. This reduction in size leads to reduced function in the gland.
