Thymus/Thymus Gland

Where is it located? What is its function?

Answer 26

Location: lies in the mediastinum, the area between the lungs, and extends upward into the lower neck

Function: Primary lymphoid organ in the upper chest that produced T lymphocytes or T cells

“The thymus is a single organ with two lobes containing lymphoid cells. The thymus appears to perform its most important work during the prenatal period and in early childhood when its size, relative to the rest of the body, is the largest. The thymus gland produces a kind of lymphocyte called a T cell (T lymphocyte). In the thymus gland, the T lymphocytes learn tolerance; that is, they learn to identify and accept the body’s antigens. (Autoimmune diseases occur when this recognition and tolerance fail and the body’s own antigens are interpreted as invading or enemy cells.) “
