Cervix

 

The cervix is the lower end of the womb (uterus). It is at the top of the vagina. It is about 2 inches (5 centimeters) 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 cervical canal also allows sperm to pass from the vagina into the uterus.

Conditions that affect the cervix include:

  • Cervical cancer
  • Cervical infection
  • Cervical inflammation
  • Cervical intraepithelial neoplasia (CIN) or dysplasia
  • Cervical polyps
  • Cervical pregnancy

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

  • Uterus

    Uterus - illustration

    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.
