When does lymphoid tissue reach adult size?

Explanation:
Lymphoid tissue enlarges as the immune system matures through childhood and adolescence. While some components like the thymus are very active in early life and then begin to involute after puberty, the overall lymphoid system reaches its adult dimensions by late adolescence. That’s why the best answer is that adult-size lymphoid tissue is achieved by the end of adolescence.
