Webb16 maj 2024 · In the alveoli (also called air sac) is the capillary-rich sac in the lungs where the exchange of oxygen and carbon dioxide takes place by diffusion. The oxygen poor blood goes from the right ventricle and into the lungs where the co2 is traded for Oxygen in the alveoli and back through the heart and out to the body. WebbAt the end of each duct are approximately 100 alveolar sacs, each containing 20 to 30 alveoli that are 200 to 300 microns in diameter. Gas exchange occurs only in alveoli. Alveoli are made of thin-walled parenchymal cells, typically one-cell thick, that look like tiny bubbles within the sacs.
