Question

Thymus increases in size with age and reaches its maximum size during puberty.

Hint:

The thymus is unique because it is the only organ that effectively "disappears" or significantly atrophies as we age after reaching peak functionality at puberty.

Answer 1

Step 1: Understanding the Concept:
The thymus is a primary lymphoid organ located near the heart, where T-lymphocytes undergo maturation.
Step 2: Detailed Explanation:
The thymus is relatively large at birth.
It continues to grow and increases in mass as the child grows, reaching its maximum absolute size at puberty.
Post-puberty, it undergoes a process called involution, where it gradually shrinks and is replaced by fat and connective tissue.
This is why immune responses weaken in old age.
Step 3: Final Answer:
True.
