Bicarbonate (HCO₃⁻) plays a crucial role in the respiratory system by helping to regulate blood pH and maintain acid-base balance. It acts as a buffer, neutralizing excess acids in the blood, which is vital for proper physiological function. During respiration, carbon dioxide (CO₂) produced by metabolism combines with water to form carbonic acid, which dissociates into bicarbonate and hydrogen ions. This process facilitates the transport of CO₂ from tissues to the lungs for exhalation while also helping to stabilize blood pH.

The main function of the respiratory system is the exchange of gases. It brings in oxygen and elmiinates carbon dioxide.
