Generally speaking, its anterior and posteriorwalls lie closely in contact, but they are capable of very wide dis-tension, as during the passage of the foetus. The anterior wall ofthe vagina is shorter than the posterior, the former measuring on anaverage 2J inches, the latter 3 inches; but the length of the canalvaries greatly in different subjects and under certain front the vagina is closely connected with the base of the bladder,so that when the vagina is prolapsed, as often occurs, it drags thebladder with it (Fig. 15); behind, it is in relation with the rectum, Fig. Longitudinal Section of Body, showing Kelatious of Generative Organs. but less intimately; laterally with the broad ligaments and pelvicfascia; and superiorly with the lower portion of the uterus and foldsof peritoneum both before and behind. The vagina is composed ofmucous, muscular, and cellular coats. The mucous lining is throwninto numerous folds.
