Labor and Delivery

The Third Stage of Labor
The third and final stage of labor brings the expulsion of the placenta and the umbilical cord from the uterus about fifteen minutes after the baby's birth. The delivery of this so called afterbirth takes only a few minutes, after which the uterus begins to shrink back to its former shape and size.
