Alveolar Gas Exchange
Color illustrations showing the gas exchange between alveolar spaces and capillaries. The cross-section of the alveolus shows the three processes are essential for the transfer of oxygen from the outside air to the blood flowing through the lungs: ventilation, diffusion, and perfusion. Red arrows indicate oxygen coming into the deoxygenated blood coming from the pulmonary artery and turning into oxygenated blood on its way to the pulmonary vein.
