And as a result, the oxygen will be much more likely to actually move from the blood of that mother and into the blood of that fetus that contains that fetal hemoglobin. Now, aside from this, there are two other factors that also facilitate the function of the placenta, facilitate the gas exchange process. So the movement of oxygen from the mother to the fetus can be facilitated by three factors. So one of them is higher affinity of fetal hemoglobin for oxygen than the adult hemoglobin. The other is the fact that inside the blood of the mother, we have a higher concentration of oxygen than inside these capillaries of that fetus. And so because of this difference in concentration, because the concentration of oxygen is naturally higher inside the blood of that mother than inside the blood of that fetus, oxygen will tend to basically move down its concentration gradient, down its pressure gradient from the mother and to that fetus.
