Description: This 3D medical animation depicts a normal vaginal birth, specifically highlighting the three stages of labor. During a vaginal childbirth, the first stage of labor lasts about 12 to 19 hours, and starts when your baby settles lower into your pelvis. At the beginning of stage two of labor, which usually lasts from 20 minutes to 2 hours, your cervix is fully dilated to 10 centimeters, and your baby's head has moved beyond the cervical opening into your birth canal. In Stage three of labor, which may last 5 to 30 minutes, mild contractions will cause the placenta, or afterbirth, to separate from the uterine wall.
