Summary
This lecture explains how the human body regulates pH, focusing on the role of the lungs in buffering excess hydrogen ions. It details the process of CO2 exchange and its impact on blood pH.

Buffering Organs in Human Body Lung: Excess hydrogen ions in the body can be buffered and eliminated from the body. H+ combines with HCO - to re-form H2CO3, which dissociates into CO2 + H2O. Some CO2 can be expired in the lungs. Change in pulmonary function can adjust blood pH for minutes to hours (...
Buffering Organs in Human Body Lung: Excess hydrogen ions in the body can be buffered and eliminated from the body. H+ combines with HCO - to re-form H2CO3, which dissociates into CO2 + H2O. Some CO2 can be expired in the lungs. Change in pulmonary function can adjust blood pH for minutes to hours (by decreasing or increasing CO2 in expiration).
