The vagina is an elastic, muscular canal with a flexible lining that provides lubrication and sensation. The vaginal canal connects the uterus and cervix to the outside world as the cervix protrudes into the vagina. During childbirth the baby passes through the vagina, also known as the birth canal. The vaginal canal also allows for menstruation and intercourse.
The vulva includes the external female genitalia including the labia (majora and minora), the opening to the vagina and urethra, the clitoris, the pubic area and the anus.
