Question

Quizplus · Accepted Answer

The carbon dioxide - carbonic acid - bicarbonate buffer system is the primary regulator of blood pH, as it maintains a balance between the concentration of carbon dioxide and bicarbonate ions in the blood. This system works by converting carbon dioxide into carbonic acid, which then dissociates into a bicarbonate ion and a hydrogen ion, effectively buffering any excess acid in the blood. Protein buffering and phosphate buffering systems also contribute to blood pH regulation, but they are not as significant as the carbon dioxide - carbonic acid - bicarbonate system. Carbonic acid itself is not a regulator of blood pH, but rather a component of the buffer system.
