The … WebAs the blood is pumped through this capillary network, gas exchange occurs. Although a small amount of the oxygen is able to dissolve directly into plasma from the alveoli, most of the oxygen is picked up by erythrocytes (red blood cells) and binds to a protein called hemoglobin, a process described later in this chapter.
WebDec 14, 2024 · When a breath is taken during inhalation, the concentration of the incoming oxygen is higher in the alveolus than in the red blood cells. For this reason, oxygen will leave the alveolus and enter the red blood cells. During exhalation, the opposite occurs.
