Were you looking for information about the Cervix? Cervex is a common misspelling of cervix.
Part of a woman's reproductive system, the cervix is located in the lower, narrow part of the uterus (womb). It connects the uterus to the vagina, and the vagina leads to the outside of the body. During a woman's menstrual period, blood flows from the uterus through the cervical canal into the vagina; during pregnancy, the cervix is tightly closed to help keep the baby inside the uterus. It also produces mucus, which helps sperm move from the vagina into the uterus.
