So we're going to be farther to the left side along the curve because in the lungs we have a lower CO2 concentration than in the tissues. And so now we're somewhere here. Now an increase in the oxygen content in our red blood cell next to the lungs means we have a rightward shift in our curve. So the black curve now shifts this way. And what that means is before this is how much CO2 was actually stored in the blood. But now this is how much CO2 can be stored in the blood.
