Thymus

✨ Overview

The thymus is a lymphoid organ located in the anterior mediastinum, behind the sternum. It is a central component of the immune system, playing a critical role in the development and maturation of T-lymphocytes (T-cells), which are essential for adaptive immunity. The thymus is most active during childhood and adolescence and gradually involutes in adulthood, but its influence on immune function persists throughout life.
