Solution
The correct option is D O2 dissociation curve
The oxygen dissociation curve plots the percentage saturation against the partial pressure of oxygen, and its contribution to the total oxygen content. This is an S-shaped curve due to the alterations in hemoglobin's affinity for oxygen in response to other physiologic factors. The dotted line at the bottom of the graph represents the dissolved O2. Dissolved O2 is a linear relationship to its partial pressure and results in a straight line. Thus the correct answer is option D.
