Tubular tract leading from the uterus to the exterior of the body in mammals. The exterior vaginal opening is the vulva. A membrane situated behind the urethral opening, the hymen?, partially occludes the vagina in many organisms, including most human females, from birth until it is ruptured by first coitus, or by any number of other activites including medical examinations, injury, certain types of exercise, introduction of a foreign object, or what-have-you. The vagina serves the dual purposes of 1) admitting the penis of the male for coitus and ultimately the introduction of male gametes (sperm) for the fertilization of ova?, and 2) providing a route to deliver a fully gestated fetus from the uterus to its independent life outside the body of the mother? in the process of [live birth]?. During birth, the vagina is referred to as the [birth canal]?. See also Vulvovaginal disorders, Vulvovaginal health
