What is the cervix?
The cervix is part of a woman's reproductive system. It's in the
pelvis. The cervix is the lower, narrow part of the uterus (womb).
The cervix is a passageway:
- The cervix connects the uterus to the vagina. During a menstrual
period, blood flows from the uterus through the cervix into the vagina.
The vagina leads to the outside of the body.
- The cervix makes mucus. During sex, mucus helps sperm move from the vagina through the cervix into the uterus.
- During pregnancy,
the cervix is tightly closed to help keep the baby inside the uterus.
During childbirth, the cervix opens to allow the baby to pass through
the vagina.
