The cervix is the opening to the womb. Itâs located between the vagina and the uterus and plays a crucial role in pregnancy and labor. During pregnancy, it remains closed and the opening is blocked with a mucus plug.
Along with your ovaries, fallopian tubes, cervix, and vagina, your uterus allows you to menstruate and become pregnant. Sometimes referred to as the womb, your uterus is the place in which your baby will develop when you become pregnant. Your uterus is located inside your lower abdomen, just between your two hip bones. Its shape is similar to that of an upside-down pear.
