And so the temperature within the blood plasma of the capillary actually drops. And what that means is if the cells are exercising less, they need less oxygen. And so the hemoglobin will be less likely to release and unload that oxygen and more likely to actually bind to that oxygen. And that's exactly why, in such a case, when we decrease the temperature we shift the entire curve to the left side with respect to the original blue curve. So in this diagram, the blue curve is our normal temperature curve, but the red curve is the lower temperature. And so we shifted entirely to the left side and at a pressure of 40 mercury inside our tissue.
