WebbFalse (viral or bacterial infection is) If the partial pressure of oxygen is higher in the alveoli than in the blood, which phrase describes the net movement of oxygen. From alveoli to blood. The ability of blood to transport oxygen is dependent on the solubility coefficient of oxygen and the presence of hemoglobin. WebbThe gradients of partial pressure of O 2 and CO 2 drive the gases to diffuse (Fig. 3.3). Inhaled O 2 diffuses from the alveoli into the capillaries, while CO 2 from the blood diffuses into the alveoli. The waste CO 2 in the alveoli is then expired through lung ventilation.
