What is the thymus? Learn about this small and important human organ

During childhood, the thymus is most active and its size peaks around puberty. As we age, the thymus tends to decrease in size and may be replaced by fatty tissue in some cases.
Although relatively small in size, the thymus is essential for the proper functioning of the immune system, helping to ensure that T cells develop correctly and become capable of recognizing and fighting foreign invaders such as viruses, bacteria and cancer cells.
Thymus: a hidden, butterfly-shaped organ
Yes, the thymus gland does indeed have a shape that is often compared to that of a butterfly, with two lobes connected by a central tissue. It is a relatively inconspicuous organ and is often described as “hidden” because it is located in the upper chest, behind the sternum, and is not easily visible or palpable externally.
Despite its modest appearance and inconspicuous position, the thymus plays a key role in the immune system, being essential for the maturation of T cells, which are vital for the body's defense against pathogens. The butterfly shape of the thymus is a reflection of its complex internal structure, which is crucial to the process of T cell development.
