Textbook Question
Chapter 39, Problem 8RQ
Of the following, which does not explain why the partial pressure of oxygen is lower in the lung than in the external air?
- Air in the lung is humidified; therefore, water vapor pressure alters the pressure
- Carbon dioxide mixes with oxygen
- Oxygen is moved into the blood and is headed to the tissues
- Lungs exert a pressure on the air to reduce the oxygen pressure.

The reason the elasticity and surface tension of the lungs do not cause the lungs to collapse between exhalation and inhalation is because
the intrapulmonary pressure is higher than the atmospheric pressure
the intrapleural pressure is less than the intrapulmonary pressure
the intrapulmonary pressure is less than the atmospheric pressure
the intrapleural pressure is greater than the atmospheric pressure
more than one of the above
Which of the following influence the diffusion of oxygen across the alveolar membrane?
the concentration of oxygen in the lungs
the concentration of carbon dioxide in the blood
the pressure of oxygen being delivered to the lungs
the pressure of exhalation of the lungs
All of the following factors increase hemoglobin's affinity for oxygen EXCEPT:
Increased temperature
Increased pH
Decreased pCO2
Decreased 2,3-DPG
All of the above increase hemoglobin's affinity for oxygen
The conduction zone:
