Cervix

Information

The cervix is the lower end of the womb (uterus). It is at the top of the vagina. It is about 2 inches long. The cervical canal passes through the cervix. It allows blood from a menstrual period and a baby (fetus) to pass from the womb into the vagina.

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

Conditions that affect the cervix include:

A Pap smear is a screening test to check for cancer of the cervix.
