Question

74. The partial pressure of O2 is the highest in alveoli​

Answer 1

Answer:

The partial pressure of O2 in alveoli is 104mm of Hg

Answer 2

$\huge\underline\mathfrak {Answer}$

The partial pressure of oxygen in alveolar air is about 104 mm Hg, whereas the partial pressure of the oxygenated pulmonary venous blood is about 100 mm Hg. When ventilation is sufficient, oxygen enters the alveoli at a high rate, and the partial pressure of oxygen in the alveoli remains high.
