The thymus gland lies beneath the sternum (breastbone) and above the trachea (wind pipe) and heart. There are two lobes to this gland and each are made of Lymphatic tissue. It establishes the immune sysetem from the time of gestation until puberty. After puberty it begins to shrink.



Thymus gland is where leukocytes aquire means to chemically identify specific foreign invaders and where Immature T cells from bone marrow move to thymus gland and mature.
