Previously, we discussed the Boar effect. And we said the Boar effect is a phenomenon by which hydrogen ions and carbon dioxide molecules bind onto special allosteric sites on hemoglobin and they decrease hemoglobin's affinity for oxygen. And what this does physiologically is it allows the hemoglobin to deliver many more oxygen molecules to the exercising tissue cells of our body. Now, what I'd like to discuss in Dyslexia is how the carbon dioxide is actually transported inside our cardiovascular system from the tissue to the lungs. And let's begin by focusing on the following diagram. So, in this diagram, we have the cells of the exercising tissue.
