Quizplus · Accepted Answer

Exchanges between fetal and maternal blood occur in the placenta, a specialized organ that connects the developing fetus to the uterine wall of the mother. The umbilical arteries and vein transport blood to and from the placenta, but the actual exchange of nutrients, oxygen, and waste products occurs across the placental membranes. The ductus venosus is a fetal blood vessel that bypasses the liver and shunts oxygenated blood from the umbilical vein directly to the inferior vena cava.
