Summary Introduction

Introduction:

The respiratory buffer system regulates the pH by increasing or reducing the breath rate and depth. Addition of carbon dioxide (CO₂) to the body fluid increases the concentration of hydrogen ions (H⁺) and reduces the pH. Elimination of CO₂ from the body fluid raises the pH. Thereby, the respiratory system buffers the acid or base when it becomes elevated. It has 2 to 3 folds strong buffering capacity when compared to chemical buffers.
