'''Parturition''' is the act of giving birth to a baby. It consists of many different stages which interact to provide delivery of child and the [[placenta]]. Childbirth usually occurs after 38 weeks of gestation (in clinical terms 40 weeks since last menstrual period), although children can be born after 24 weeks with some hope of survival (this is known as a preterm birth). Parturition tends to last between 8 hours (in multiparti mothers) to 14 hours (in primipari mothers), although longer labours are not unusual.

'''Stage Three''' is associated with the delivery of the placenta. Because of the importance of completely removing the entire placenta (abandoned villi can result in maternal haemorrhage) this stage is usually assisted with steady traction on the umbilical cord and doses of oxytocin.
