Where is the thymus located?
Quick Answer
The thymus is located in the upper chest, behind the breastbone and in front of the heart. It is especially active during childhood.
The Full Story
The thymus lies in the upper anterior mediastinum, behind the sternum and above the heart. It is a key organ of the immune system because T cells mature there. The thymus is largest and most active in children and gradually shrinks after puberty. Even as it shrinks, its early role is crucial for immune development.
