Partial pressure is a way to measure the concentration of oxygen. The two arrows show the concentration of oxygen in the tissues and in the lungs. Why do you think the percent oxygen is high in the lungs and low in the tissues (1 sentence)? b. Hb % saturation is the percent of hemoglobin molecules that have bound oxygen. At 100% saturation, all of the oxygen-binding sites of hemoglobin are bound. The graphs shows two lines depicting how saturated hemoglobin would be at the different oxygen concentrations in an environment of pH7.2 (lower line) and 7.4 (upper line). Is hemoglobin in the tissues (i.e. 40 pp oxygen) more likely to be saturated at 7.2 or 7.4 (circle one)? c. In 1-2 sentences, summarize what the two lines in the graph tell you about hemoglobin's response to changes in pH. 5. Delivering oxygen to your tissues is a pretty important iob. Since pH afects that ioh it is easy
