In fetal circulation, the placenta is where blood from the mother exchanges gases and nutrients with the fetus. The vessel that carries blood from the placenta to the fetus is the umbilical vein. It delivers oxygenated, nutrient-rich blood into the fetal circulation, supplying the heart and body. Two umbilical arteries carry blood in the opposite direction—from the fetus to the placenta. The other two structures mentioned serve different roles: the ductus arteriosus is a fetal shunt between the pulmonary artery and aorta, and the hepatic portal vein carries nutrient-rich blood from the gut to the liver.
