Cervical Cancer

The cervix is part of a woman's reproductive system. It is the lower, narrow part of the uterus (womb). The uterus is a hollow, pear-shaped organ in the lower abdomen. The cervix connects the uterus to the vagina. The vagina leads to the outside of the body.
The cervical canal is a passageway. Blood flows from the uterus through the canal into the vagina during a woman's menstrual period. The cervix also produces mucus. The mucus helps sperm move from the vagina into the uterus. During Pregnancy, the cervix is tightly closed to help keep the baby inside the uterus. During childbirth, the cervix dilates (opens) to allow the baby to pass through the vagina.
