Resistance in the pulmonary circulation is very high because the lungs are collapsed and filled with fluid.Oxygen and nutrients are carried to the fetus by the umbilical vein.The inferior vena cava empties blood into the right atrium.The direction of blood flow and the pressure in the right atrium propel most of this blood through the foramen ovale into the left atrium.Most of the blood in the pulmonary artery flows though the ductus arteriosus into the descending aorta.
