What is the significance of the sigmoidal relationship between Po2 levels and hemoglobin saturation?

+1 vote

 

  

As tissue Po2 levels drop below 40 mm Hg, the amount of oxygen released by hemoglobin increases disproportionately.

  

As tissue Po2 levels decline with an increase in activity, hemoglobin saturation increases.

  

As it circulates, hemoglobin releases the same amount of oxygen to all tissues.

  

As tissue Po2 levels decline, the amount of O2 released increases proportionately.
