Splet07. jan. 2024 · Remember the pores of Kohn from your A&P class? Those were the little “doorways” that exist between alveoli. Having higher pressures at end expiration enables us to essentially open those doorways and access neighboring alveoli. In other words, we are “recruiting” the neighboring alveoli for gas exchange through the pores of Kohn. Splet30. jul. 2024 · Gas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up. External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs.
