What is the connecting link between the uterus and the vagina?
Cervix
The uterus is also called the womb. The cervix is the lower part of the uterus that connects the uterus to the vagina. The function of the cervix is to allow the flow of menstrual blood from the uterus into the vagina. It also aids in carrying sperm from the vagina to the uterus. It also widens during childbirth to allow the passage of the baby.
