Vagina

The vagina is an elastic, muscular reproductive organ of the female genital tract in mammals. It is involved in copulation and birth. In humans, it extends from the vulval vestibule to the cervix and also channels menstrual flow. During sexual intercourse, its walls produce lubrication and friction that can stimulate the penis toward ejaculation. The term is often incorrectly used in common speech to mean the vulva or female genitals generally.
