The human vagina is a muscular, elastic tubular structure that extends from the external vulva to the cervix of the uterus. It is lined with mucous membranes, which help maintain moisture and balance pH levels, and features rugae (folds) that allow for expansion during intercourse and childbirth. The vagina has a pH that is typically acidic, which helps protect against infections. Its structure also includes various glands that secrete fluids to aid in lubrication.
