WebSep 7, 2024 · The Bohr shift helps the body release more O2 to respiring tissues when the blood pH is more acidic. During exercise, a lot of CO2 is produced, which results in larger amounts of hydrogen ions that acidify the blood. Thus, the Bohr shift lets the body know it's exercising. Explain how and why ventilation rate varies with exercise. WebBohr shift effect.
