Quizplus · Accepted Answer

The umbilical cord connects the developing embryo/fetus to the placenta, which is responsible for providing nutrients, oxygen, and water to the developing baby, and removing waste such as carbon dioxide. The amniotic sac contains amniotic fluid that surrounds and protects the developing baby, but it does not play a role in delivering nutrients or removing waste. The zygote is the initial cell formed by the fusion of sperm and egg, but it does not have any role in delivering nourishment or removing waste.
