Question

Quizplus · Accepted Answer

The placenta is an organ that develops from the lining of the uterus and is responsible for the exchange of nutrients, oxygen, and waste products between the mother and the developing embryo. Oxygen and nutrients are transported from the mother's blood vessels to the placenta, and then across the placental membrane to reach the embryo. Waste products, such as carbon dioxide and urea, are transported in the opposite direction, from the embryo to the mother, to be eliminated. Therefore, the placenta is the site of nutrient and gas exchange between the mother and the developing fetus during pregnancy. The amnion, chorion, and zona pellucida are also involved in the development of the embryo, but they do not play a direct role in nutrient and gas exchange. The uterine sac is not a recognized anatomical structure.
