A) is normally the primary factor determining the amount of flow into/out of the lungs. B) is increased when the diameter of the airways becomes reduced. C) when elevated requires an increased pressure gradient between the lungs and atmosphere through vigorous respiratory efforts to move even normal volumes of air into and out of the lungs. D) both (b) and (c) above. E) all of these answers. A) is normally the primary factor determining the amount of flow into/out of the lungs.

A) combines preferentially with O2 over any other substance. B) when combined with carbon dioxide is known as carboxyhemoglobin. C) plays a critical role in determining the amount of O2 that is exchanged between alveoli and blood, because it acts as a storage depot, removing dissolved O2 from the blood thereby keeping PO2 low and allowing net diffusion of O2 to continue until the hemoglobin is completely saturated.
