bicarbonate buffer

The bicarbonate buffer is a crucial system in our body that helps maintain stable pH levels in our blood and fluids. It works by balancing acids and bases using bicarbonate (HCO3-) and carbon dioxide (CO2). When an acid enters the blood and lowers pH, bicarbonate can neutralize it, preventing the blood from becoming too acidic. Conversely, if the blood becomes too basic, carbonic acid can release hydrogen ions to restore balance. This buffering system is essential for proper cellular function and overall health, ensuring our body's environment remains stable despite various physiological changes.

    The bicarbonate buffer system is a crucial part of our body's way of maintaining a stable pH, which is essential for proper cellular function. It primarily involves bicarbonate ions (HCO₃⁻) and carbonic acid (H₂CO₃). When the blood becomes too acidic, bicarbonate can neutralize the excess acid by forming carbonic acid, which then breaks down into water and carbon dioxide. Conversely, if the blood is too alkaline, carbonic acid can release hydrogen ions to lower the pH. This balance helps regulate acidity in the blood and is vital for overall health.
