Question

Quizplus · Accepted Answer

The placenta is a structure made of tissues from both the mother and the embryo/fetus, where small blood vessels from both intertwine but do not join. It allows for the exchange of nutrients, gases, and waste between the mother and the embryo/fetus. The amnion is a fluid-filled sac that surrounds and protects the embryo/fetus. The embryo is the developing organism during the first 8 weeks of pregnancy. The umbilical cord is a structure that connects the embryo/fetus to the placenta, allowing for the exchange of nutrients and waste.
