Vedclass · Answer

(D) The $Thymus$ gland is a lobular structure located between the lungs behind the sternum on the ventral side of the aorta.It plays a major role in the development of the immune system.This gland secretes the peptide hormone $Thymosin$,which promotes the differentiation of $T$-lymphocytes,providing cell-mediated immunity.In addition,$Thymosin$ also promotes the production of antibodies to provide humoral immunity.As a person ages,the $Thymus$ undergoes gradual degeneration (atrophy),resulting in a decreased production of $Thymosin$.Consequently,the immune responses of older individuals become weaker.

The immune responses in older people are weak due to the degeneration of which endocrine gland?
