This is different from male mammals, who usually have a single urethral opening for both urination and reproduction.The vaginal opening is much larger than the nearby urethral opening, and both are protected by the labia in humans.By its dictionary and anatomical definitions, however, vagina refers exclusively to the specific internal structure, and understanding the distinction can improve knowledge of the female genitalia and aid in healthcare communication.Although by its dictionary and anatomical definitions, the term vagina refers exclusively to the specific internal structure, it is colloquially used to refer to the vulva or to both the vagina and vulva.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.In amphibians, birds, reptiles and monotremes, the cloaca is the single external opening for the gastrointestinal tract, the urinary, and reproductive tracts.To accommodate smoother penetration of the vagina during sexual intercourse or other sexual activity, vaginal moisture increases during sexual arousal in human females and other female mammals.

The lateral walls, especially their middle area, are relatively more rigid.Although research on the vagina is especially lacking for different animals, its location, structure and size is documented as varying among species.Female mammals usually have two external openings in the vulva, the urethral opening for the urinary tract and the vaginal opening for the genital tract.The opening of the vagina lies in the urogenital triangle.The urogenital triangle is the front triangle of the perineum and also consists of the urethral opening and associated parts of the external genitalia.
