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.
