The chorion.
The two structures that are part of the afterbirth are the placenta and the umbilical cord. The placenta facilitates nutrient and gas exchange between the mother and the fetus during pregnancy, while the umbilical cord connects the fetus to the placenta, providing a lifeline for nutrients and waste removal. After childbirth, these structures are expelled from the body, marking the end of the delivery process.
