What happens during the three stages of childbirth?
What will be an ideal response?
First, uterine contractions efface and dilate the cervix to allow the fetus to pass through
the birth canal. The first stage is the longest stage, and as it progresses, the
contractions become more regular and intense. When the cervix is fully dilated, to
approximately 10 cm, transition occurs. That is, the head of the fetus begins to move
into the vagina or birth canal. The process of transition usually lasts 30 minutes or less.
The second stage of childbirth begins when the head of the fetus can be seen at the
opening of the birth canal. Once the fetus's head has crowned, the fetus usually
emerges from the birth canal in a matter of minutes. Mucus is usually suctioned from
the infant's mouth after the head emerges to clear the passageway for breathing.
When the infant is breathing on his or her own, the umbilical cord is clamped and
severed. The mother and infant are now separate individuals. The third stage lasts for
minutes up to an hour or more.During this stage, the placenta is expelled from the
vagina.
