Question

Describe what causes CO2 to leave RBC at the lungs.

Accepted Answer

Formation of CO2 gas at the lungs:Haemoglobinic acid dissociates into H+ and HbHydrogencarbonate ions diffuse back into RBC and react with hydrogen ions to form carbonic acid, chloride ions diffuse outThis is broken down to release free CO2 (carbonic anhydrase) that diffuses out of blood into lungs down a concentration gradient
