Blood pH Regulation

Blood pH regulation is crucial for maintaining the body's balance of acids and bases. The normal pH range of blood is about 7.35 to 7.45. The body uses three main systems to regulate pH: the buffer systems, breathing, and the kidneys. Buffers in the blood neutralize acids and bases quickly. The lungs can adjust carbon dioxide levels through breathing, which affects acidity. The kidneys manage the excretion of excess acids or bases over longer periods. Together, these mechanisms keep blood pH stable, allowing vital biochemical processes to function properly.
