What do the vagina and cervix comprise during childbirth?

During childbirth, the vagina and cervix together create what is known as the birth canal. This pathway allows the baby to move from the uterus, through the cervix, and out of the vagina during delivery. The cervix dilates to allow the passage of the baby, and the vagina serves as the channel for delivery.

The birth canal is a critical component of the birthing process, and its structure is specifically adapted for this purpose, as it must accommodate the size of the fetus and provide a safe route for delivery. Understanding this function is crucial for emergency medical responders, as they may need to assist with childbirth situations.
