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.
No, the embryonic sac and the placenta are not the same thing. The embryonic sac, or amniotic sac, is a fluid-filled structure that surrounds and protects the developing embryo. In contrast, the placenta is an organ that forms during pregnancy, providing nutrients and oxygen to the fetus and removing waste products. While both are crucial for fetal development, they serve different functions and structures.
