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.

A mouse is placed in a sealed chamber with air at 754.0 torr. This chamber is equipped with enough solid KOH to absorb any CO2 and H2O produced by the mouse. The gas volume in this chamber is measured to be exactly 2.00 L, the temperature is held constant at 295 K. After two hours the pressure inside the bottle falls to 717.4 torr. What mass of oxygen has the mouse consumed?

The atmospheric pressure on the top of Mt. Everest, an altitude of 29,035 ft, is only 259.9 mm Hg. What is the partial pressure of oxygen in the lungs at this altitude (assuming that the % O2 is the same as in dry air, 20.88%)? Report the pressure to the tenths of a mm Hg without units.

Exhaled air is ordinarily at body temperature and 100% humidity (i.e., it is fully saturated with water). Estimate the mass of H2O that is lost each day because of normal breathing. The saturation vapor pressure (SVP) of water at 37℃ is 47 mmHg and contains 44 mg/L of water, whereas at room temperature (20℃) it is 20 mmHg and contains only 18 mg/L.
