A vagina is the female sex organ. As the organ of sexual response, it accommodates the penis during copulation. The infant goes through it during childbirth. Furthermore, the organ serves as the passageway for menstrual fluids from the uterus.
A vagina links to the uterus, a pear-shaped hollow organ situated between the rectum and the bladder. The cervix, which serves as the channel between the vagina and uterus, projects into the vagina.
External structures, known as the vulva and labia, front the vagina. A superficial layer of tissue, called the hymen, partly constricts the vaginal opening. But it can be torn apart by sexual activities and exercising.
