Structure & Function
Cervical Cancer

 

The cervix is the part of the female reproductive system that connects the uterus (womb) to the vagina.

It is the lower most part of the uterus and is made up of strong muscles.

The function of the cervix is to allow flow of menstrual blood from the uterus into the vagina, and direct the sperms into the uterus during intercourse.

The opening of the cervical canal is normally very narrow. However under the influence of the body hormones and the pressure from the fetal head, this opening widens to about 4 inches (10 cm.) during labor, to allow the birth of a baby.

If the opening is loose, as observed in some women, it can lead to miscarriages during pregnancy.
