Now, the blue curve describes our oxygen hemoglobin dissociation curve at a normal body temperature of about 37 36.7 degrees Celsius. But the red curve describes the same exact curve, but at a slightly higher temperature. And notice that the red curve is shifted to the right compared to our left curve compared to our blue curve. And that's exactly what happens when we increase the temperature of our blood plasma. We shift the entire curve to the right. The question is why?
