"Webb8 juni 2024 · More specifically, alveolar PO 2 is higher in the alveoli (P ALV O 2 =100mmHg) than blood PO 2 in the capillaries (40mmHg). Since this pressure gradient exists, oxygen can diffuse down its pressure gradient, moving out of the alveoli and entering the blood of the capillaries where O 2 binds to hemoglobin.
