And by decreasing our hemoglobin's ability to bind to oxygen, we ultimately shift the entire oxygen hemoglobin dissociation curve to the right, as seen in the following diagram. And this is known as the Bore Effect. So by increasing the concentration of carbon dioxide, we ultimately increase the concentration of H plus ions, and that makes our blood more acidic. So we decrease our PH, and this causes a decrease in our hemoglobin's ability to bind to oxygen, thereby shifting the entire curve to the right side with respect to the original curve shown in blue. So the blue curve is the oxygen hemoglobin dissociation curve when the PH is 7.4. So when our tissue is not exercising, but if the tissue begins to exercise, that means we produce more H plus ions, and that shifts the entire curve to the right.
