The thymus gland, located behind the sternum and between lungs, is only active until puberty. After puberty, the thymus starts to slowly shrink and become replaced by fat. Thymosin is the hormone of the thymus, and it stimulates the differentiation of disease-fighting T cells.
A person without thymus would not be able to

Receive a tissue transplant
-
Develop an inflammatory response
-
Produce antibodies
If thymectomy is done during adult hood then what possibility is there?

The thymus gland plays an important role in the immune function of the body by acting as an reservoir for T cells. Thymectomy or removal of the thymus gland in new born does not show any effect. However, the removal of the thymus gland during adulthood will result in suppression of the immune system.
Which glands helps to maintain immunity
-
Hypothalamus
-
Adrenal
-
Thymus
-
Pancreas
Thymosins secreted by thymus play a major role in the differentiation of T-lymphocytes, which provide cell-mediated immunity. In addition, thymosins also promote production of antibodies to provide humoral immunity.
Hassall corpuscles are characteristic of
-
Thymus
-
Adrenal
-
Pineal
-
Pancreas
Hassall's corpuscles also called thymic corpuscles, are structures found in the medulla of the human thymus, formed from eosinophilic type VI epithelial reticular cells, arranged concentrically.
Thus, the correct answer is option (A), 'Thymus'.

The gland which is related to the maturation of lymphocytes is
-
Thymus
-
Thyroid
-
Adrenal
-
Pituitary
Thymus is small lymphoid structure present in lower art of neck in front of trachea, below the thyroid gland. It is the primary source of lymphocytes before birth and is the site of maturation or development of T-lymphocytes which circulates in lymphoid tissues.
Which endocrine gland becomes inactive after puberty?
-
Thyroid
-
Parathyroid
-
Thymus
-
Gonads
Thymus becomes inactive after puberty and shrinks. Most of the glands is replaced by adipose tissue. It produces thymosin which stimulates the development of disease-fighting T cells. The immune system produces most of its T cells during childhood and requires very few new T cells after puberty so the gland degenerates.

Or
Which one of the following is gradually reduced and degenerated in ageing according to immunity theory
Or
Which is called "Clock of ageing"
-
Thyroid
-
Parathyroids

-
