The amnion and the chorion are two essential fetal membranes that play distinct roles during pregnancy. The amnion is the innermost membrane that envelops the developing fetus and is responsible for forming the amniotic sac, which contains the amniotic fluid that surrounds and cushions the fetus. This fluid offers protection and helps regulate temperature, allowing the fetus to move and develop without constraints. The amnion also aids in preventing infections from reaching the fetus.

In contrast, the chorion is the outermost fetal membrane that develops from the trophoblast cells and surrounds the amnion. It contributes to the formation of the placenta, a crucial organ for nutrient and gas exchange between the mother and fetus. The chorion is involved in the attachment of the placenta to the uterine wall and assists in the exchange of waste products and nutrients between the maternal and fetal bloodstreams.

In summary, the amnion and the chorion serve distinct functions during pregnancy. The amnion forms the amniotic sac, protecting the fetus and providing a suitable environment for growth, while the chorion contributes to placental formation and facilitates nutrient and waste exchange between the mother and fetus.
