Question

Quizplus · Accepted Answer

The umbilical vein carries oxygenated blood from the placenta to the fetus, whereas the umbilical artery carries deoxygenated blood from the fetus to the placenta. The aorta carries oxygenated blood from the left ventricle of the heart to the rest of the body, while the pulmonary trunk carries deoxygenated blood from the right ventricle of the heart to the lungs. The common iliac arteries carry oxygenated blood to the lower limbs. Therefore, the only fetal blood vessel that carries fully oxygenated blood is the umbilical vein.
