Location It is on the lower centre of the vulva. It is the tube leading from the uterus (womb) to the outside of the body. The opening is found between the legs, inside the labium, behind the opening to the urethra, a tube leading to the bladder, and in front of the anus, the opening to the rectum.
[change]Anatomy The vagina is an elastic, muscular tube starting from the cervix and ending at the vulva.[1] It is about 6 to 7.5 cm (2.5 to 3 in) wide, and 9 cm (3.5 in) long.[2] During sexual intercourse and childbirth, the vagina gets wider and bigger.[3]
The vagina has to be lubricated to stay clean and allow sexual intercourse and childbirth. It is lubricated by the Bartholin's glands. This mucus also allows sperm easier access to fertilize an ovum.
