1.  As mentioned in the introduction to this activity, hemoglobin levels increase for people living at high altitudes. Given that the atmospheric pressure of oxygen significantly declines as you ascend to higher elevations, why do you think hemoglobin levels would increase for those living at high altitudes?


2. Just looking at the color of a freshly drawn blood sample, how could your distinguish between blood that well oxygenated and blood that is poorly oxygenated?

I need help with these 2 questions please

Its necessary for the hemoglobin at higher altitudes to have a greater affinity for the oxygen in the atmosphere because there is less of it readily available.  In order for the body to be able to supply the body with sufficient oxygen, it must have a high affinity to grab what it needs from a limiting atmosphere and process it to the tissues. 

Less available must increase the affinity!!!
