Скачать или смотреть Gas Exchange Part 3 Carbon Dioxide Exchange at Tissues & Lungs. Carbonic Acid Reaction. Bohr Effect.

This videos starts by explaining how carbon dioxide moves from the tissues into the blood. In doing this, it explains the carbonic acid reaction and the purpose of it. It then discusses how carbon dioxide moves from blood into the alveoli and explains how and why the carbonic acid reaction reverses in this process. Next it attempts to create a full picture by briefly explaining how the exchange of carbon dioxide and oxygen happens simultaneously at the lungs and tissues. It finishes by explaining how changes in pH (acidity) and temperature influence the exchange of oxygen.
