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.
