What are the three stages of birth?

The three stages of birth are:

1. Labor

This is the longest stage of birth, and it begins with the onset of regular uterine contractions. These contractions gradually increase in intensity and frequency, and they eventually cause the cervix to dilate (open) enough to allow the baby to pass through. The first stage of labor ends when the cervix is fully dilated.

2. Delivery

This is the stage during which the baby is born. Once the cervix is fully dilated, the mother begins to push. The pushing contractions help to move the baby down the birth canal and out of the mother's vagina. The second stage of labor ends when the baby is born.

3. Placental delivery

This is the final stage of birth, and it occurs after the baby is born. The placenta is the organ that provides nourishment to the baby during pregnancy. After the baby is born, the placenta detaches from the uterine wall and is expelled from the mother's vagina. The third stage of labor ends when the placenta is delivered.
