Information Return to top

The cervix is the lower end of the uterus. It is located at the top of the vagina and is about one inch long. The cervical canal passes through the cervix, allowing blood from a menstrual period and a baby (fetus) to pass from the womb (uterus) into the vagina.

The cervical canal also allows sperm to pass from the vagina into the uterus.
