WebAs shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli. Three processes are essential for the transfer of oxygen from the outside air to the blood flowing through the lungs: ventilation, diffusion, and perfusion. WebAnd then they pick up the oxygen from inside the alveoli-- or the oxygen diffuses across the membrane of the alveoli, into these capillaries, into these super small tubes. And then once they do, that makes the blood red. ... they sop about 98.5% of the oxygen. So these red blood cells are just traveling and they're going to go back to the heart ...
