So we're about somewhere right here. Now, if we check out the corresponding Y value, we'll see that the percent saturation of hemoglobin at that partial pressure drops. Now, what does that mean? Well, that basically means when our red blood cells carrying the hemoglobin arrive at the tissues that hemoglobin, some of that hemoglobin will unload that oxygen and the oxygen will readily transfer to the tissues as a result of that difference in partial pressure. And so what this graph tells us is our percent saturation will be somewhere in the 70s, which is lower than what it is within our lungs. Within the lungs, it's about 98% because most of that oxygen is picked up.
