labor

the function of the female organism by which the product of conception is expelled from the uterus through the vagina to the outside world.

Labor may be divided into three stages. The first stage (dilatation) begins with the onset of regular uterine contractions and ends when the cervical os is completely dilated and flush with the vagina, thus completing the birth canal. The second stage (expulsion) extends from the end of the first stage until the expulsion of the neonate is completed. The third stage (placental) extends from the expulsion of the neonate until the placenta and membrane are expelled and contraction of the uterus is completed. Called also parturition.
