Quizplus · Accepted Answer

Isohydric buffering and pulmonary ventilation are key mechanisms in maintaining stable pH levels despite the production of CO2. Isohydric buffering involves chemical systems in the blood that immediately neutralize changes in pH, while pulmonary ventilation removes CO2, a major product of metabolism that can acidify the blood, from the body through exhalation. Gastrointestinal secretion, although it plays a role in eliminating some substances from the body, is not directly involved in the regulation of blood pH in the context of CO2 production.
