Answer:

The three stages of labor are active labor, birth of the baby, and delivery of the placenta. Active labor lasts an average of 8 hours and is when the baby begins to descend. The cervix dilates from 4 to 10 centimeters through contractions. The birth of the baby is when the cervix has reached the maximum 10 centimeters and the mother starts pushing the baby's head out. This stage may last from minutes to hours. The final stage is the delivery of the placenta, which includes mild contractions and lasts on average 5 to 10 minutes. The umbilical cord and the placenta are delivered vaginally.
