Detailed explanation-1: -How big is the thymus gland? The thymus gland is quite big in babies and children. It reaches its biggest weight of about 1 ounce during puberty. After puberty, it begins to shrink, and in older adults, it’s rather small.
Detailed explanation-2: -The thymus is a vital yet unusual organ. Vital in that it is responsible for producing immune cells; unusual in that it is largest at childhood and progressively shrinks after puberty. The result is less T cell production, which should lead to a higher risk of infection or cancer.
Detailed explanation-3: -Assertion :The thymus gland is quite large in size at the time of birth but shrinks in size with age. Reason: Immune system produces most of its T cells during childhood and requires very few new T cells after puberty.
