And that increases the number of CO2 molecules in this form that we can store and dissolve in the blood plasma of the nearby capillary. Now we can also represent this effect graphically. So let's take a look at the following graph. The y axis is basically the CO2 content in the blood, dissolved in the blood. And the x axis is the partial pressure of the carbon dioxide in that region in the blood. Now this relatively straight line, the black curve, basically describes how much carbon dioxide we can fit, we can dissolve inside the blood at some given partial pressure of carbon dioxide.
