Quizplus · Accepted Answer

The placenta is the primary site of nutrient, gas, and waste exchange between the pregnant female mammal and the developing fetus. The placenta is a specialized organ that develops within the uterus during pregnancy and is responsible for the exchange of nutrients, oxygen, and waste products between the mother's blood supply and the fetal blood supply. The umbilical cord connects the fetus to the placenta and serves as a conduit for the exchange of materials. Blood islands and yolk sac are associated with early embryonic development, while the amnion is a membrane that surrounds and protects the developing fetus.
