Quizplus · Accepted Answer

The placenta is the temporary organ that functions in the exchange of gases, nutrients, and wastes between maternal and fetal blood. The umbilical cord connects the fetus to the placenta, but does not play an active role in the exchange of substances. The amnion is a membrane that surrounds and protects the developing fetus, but does not directly participate in the exchange of substances. The yolk sac is an embryonic membrane that provides nutrients to the developing embryo, but it does not have a role in fetal development in mammals.
