Quizplus · Accepted Answer

I and III, 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 buffer 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 does not play a direct role in the immediate regulation of blood pH in response to CO2 production.
