<P> The thymus enlarges during childhood , and atrophies at puberty . Unlike many other organs , the thymus is at its largest in childhood . The thymus reaches maximum weight ( 20 to 37 grams ) by the time of puberty . The thymus of older people is scarcely distinguishable from surrounding fatty tissue . With aging the thymus slowly shrinks , eventually degenerating into tiny islands of fatty tissue . By the age of 75 years , the thymus weighs only 6 grams . In children the thymus is grayish - pink in colour and in adults it is yellow . </P>
