Cervix

The cervix is the lower end of the womb (uterus). It is at the top of the vagina. It is about 2.5 to 3.5 centimeters (1 to 1.3 inches) long. The cervical canal passes through the cervix. It allows blood from a menstrual period and a baby (fetus) to pass from the womb into the vagina. The sperm travel up the cervical canal, then through the uterine cavity into the fallopian tubes to fertilize the egg.

The cervical canal also allows sperm to pass from the vagina into the uterus.

Conditions that affect the cervix include:

A Pap smear is a screening test to check for cancer of the cervix.

Uterus - Illustration Thumbnail

Uterus

The uterus is a hollow muscular organ located in the female pelvis between the bladder and rectum. The ovaries produce the eggs that travel through the fallopian tubes. Once the egg has left the ovary it can be fertilized and implant itself in the lining of the uterus. The main function of the uterus is to nourish the developing fetus prior to birth.
