Afterbirth

 

in humans and other placental mammals, the placenta and fetal membranes (the amnion and chorion) expelled from the uterus after the delivery of an infant. The afterbirth also includes the umbilical cord. The afterbirth usually is expelled completely after the infant is delivered. If it does not emerge completely, the parts remaining in the uterus must be removed manually.
