Question

Write short on the functions of thymus.

Answer 1

The thymus actively secretes the hormones called thymosins (only till pre-pubescence) Thymosins are peptide hormones which play an important role in

• The stimulation, development and differntiation of T-lymphocytes.
• The development of cell-mediated immunity (T-lymphocytes mediated immunity)
• The production of antibodies (Humoral immunity).

Thymosin secretion is completely absent in old individuals because of which their immunity becomes weak.
