Why does the thymus shrink with age and what impact does this have on the immune system?
The thymus shrinks with age because it gradually loses its ability to produce new T cells, which are important for the immune system. This can weaken the immune response and make the body more vulnerable to infections and diseases.
When is the thymus most active?
The thymus is most active during childhood and adolescence. It plays a crucial role in the development and maturation of T cells, which are important for immune function. As we age, the thymus gradually shrinks and becomes less active.
What gland atrophies as the person ages?
The thymus atrophies with age -- in youth it is responsible for building up a stockpile of T cells, and it begins to atrophy once it stops production. It then takes on a smaller role of stimulating the immune system -- at birth, the thymus weighs approx 15 grams. During puberty it weighs approx 35 grams. By age 25, it drops down to 25 grams, and by age 60 it weighs a mere 1/2 gram.

What happen to the thymus gland when you get older?
The thymus gland tends to shrink in size and become less active as you get older. This process is known as involution of the thymus, which can impact the production of T-cells that play a crucial role in the immune system.
