If the atmosphere contains 21% oxygen at 730 mm Hg, then the partial pressure of oxygen would be:
Homework Answers
Ans) Since inspired air is 21% oxygen and atmospheric pressure is 730 mmHg (at sea level), the partial pressure of oxygen is 0.21 x 730 mmHg = 153.3 mmHg.
- As air moves into the alveoli, water vapor and carbon dioxide are added, and that reduces the partial pressure of oxygen to about 100 mmHg in the alveolar gas.
