Alveolus Cells and Capillaries of the Lung

“Alveolus Cells and Capillaries of the Lung”  shows an alveolus with single cell lining and associated arteriole, capillary and venous circulation.  The cool fresh air flows into the alveolus, and oxygen flows into the blue blooded arteriole converting into a red blooded venule.  A breeze of carbon dioxide flows through the single celled alveolus and into the airways for expiration
