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. hunstanton holiday accommodationSpletGas exchange occurs in the alveoli where oxygen is exchanged with carbon dioxide between the alveoli and the blood in the capillaries. This is driven by the change in partial pressure from the alveoli to the capillaries. martyna thomas
