Summary Introduction
Introduction:
The thymus is one of the three main lymphatic organs. It continuously grows until puberty, when it reaches a maximum weight of 30 to 50 grams. The maturation of T cells takes place within the thymus. It secrets a hormone called thymosin that is important in the process of T-cell maturation.
