To compare: A dissociation curve for hemoglobin and adaptation to living where air is “thin”. The curve showing the percentage of saturation (the amount of O 2 bound to hemoglobin) at increasing values of P0 2 . Partial pressure reflects the relative amount of gas in a mixture and is measured in millimeters of mercury 9mmHg). Llamas are native to the Andes Mountains in South America. The partial pressure of O 2 in the atmosphere where live is about half of the PO 2 at sea level. As a result, the PO 2 in the lungs of llamas is about 50mm Hg, whereas that in human lungs at sea level is about 100mm Hg. Concept introduction: The hemoglobin pigment act as a vehicle for transport of oxygen in blood. The oxygen-hemoglobin dissociative curve is a curve that shows the percentage of saturated hemoglobin on the y- axis and succeeding oxygen tension on the x-axis. This curve helps in understanding the carrying and release of oxygen by blood.
