Solution
- The partial pressure is the pressure exerted by a particular gas within a mixture of gasses. The partial pressure of carbon dioxide at alveoli is about 40 mm of Hg and partial pressure of carbon dioxide at oxygenated blood is about 45 mm of Hg. Similarly, partial pressure of oxygen at alveoli is about 104 mm Hg.
Thus, the correct answer is '40, 45.'
