This application contains Interesting and True Facts About Vagina.
In mammals, the vagina is the fibromuscular, tubular part of the female genital tract extending, in humans, from the vulva to the cervix. The outer vaginal opening is normally partly covered by a membrane called the hymen. At the deep end, the cervix (neck of the uterus) bulges into the vagina. The vagina allows for sexual intercourse and childbirth, and channels menstrual flow (menses), which occurs as part of the monthly menstrual cycle.
