Question

Quizplus · Accepted Answer

The chorion is the extraembryonic membrane that eventually forms the fetal side of the placenta. The amnion surrounds the developing embryo and helps to protect it with amniotic fluid. The allantois helps with waste disposal and eventually contributes to the formation of the umbilical cord. The yolk sac is involved in the early development of the digestive and circulatory systems, but does not contribute to the formation of the placenta.
