Which gland secretes thymosins, hormones that help in the development of T-lymphocytes?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Thymus
The thymus, a lobed gland lying near the heart, secretes thymosins, which help T-lymphocytes to develop and so build up the body’s immunity. The thymus shrinks in old age, which weakens immune responses.
