What is the cervix?

The cervix is the lower part of the uterus, which is the female reproductive organ that holds a baby during pregnancy. The cervix connects the uterus and the vagina. The vagina leads to the outside of the body. Both the uterus and the cervix are located in the pelvis. They are in close contact with other pelvic organs, such as the ovaries, upper part of the vagina, bladder, and rectum.
