Question
Which endocrine gland becomes inactive in old age
Adrenal
Thymus
Pineal
Pituitary
Solution
B.
Thymus
A critical immune organ called the thymus shrinks rapidly with age, putting older individuals at greater risk for life-threatening infections. A new study reveals that thymus atrophy may stem from a decline in its ability to protect against DNA damage from free radicals. The damage accelerates metabolic dysfunction in the organ, progressively reducing its production of pathogen-fighting T cells.
