Suppose that the partial pressure of oxygen in the alveoli is doubled from its normal value of 14 kPa. What would then be the partial pressure of oxygen dis- solved in the blood leaving the alveoli? A. 7 kPa B. 14 kPa C. 21 kPa. D. 28 kPa.
Option A. The quantity of a gas that will dissolve in a liquid this is in contact with the gas is decided with the aid of using the partial pressure of that gas . If pp of O is 14 kPa × 2, then the concentration of O this is dissolved in blood withinside the alveolar capillaries is likewise 28 kPa.
