Eventually, that deoxygenated blood will enter these internal iliac arteries and they will connect with these umbilical, arteries, and that will carry the deoxynated blood back into the placenta. And once again, inside the placenta, we have the oxygenation of that blood and the nutrients flow into that blood once again. And so the fetal blood now contains the oxygen nutrients, and the cycle can basically start over again. So this is the way that blood circulates inside that developing fetus before the birth of that fetus. So we have three important shunting processes taking place. And the reason we need the shunting processes is because the liver and the lungs are not functional in that developing fetus.
