If the partial pressure of oxygen in the air contained in the alveoli of the lungs is 14 kPa, then the partial pressure of oxygen dissolved in the alveolar fl uid will be: A. Very close to 14 kPa B. Signifi cantly greater than 14 kPa C. Signifi cantly less than 14 kPa. D. Unable to be determined without the solubility coeffi cient of oxygen and the temperature of the alveolar fl uid.
Option A. If the partial pressure of oxygen in the air contained in the alveoli of the lungs is 14 kPa, then the partial pressure of oxygen dissolved in the alveolar fl uid will be very close to 14pka.
