What is the typical pH range for normal blood?

The typical pH range for normal blood is between 7.35 and 7.45. This range is essential for maintaining homeostasis in the body, as many biochemical processes, including enzyme activity and oxygen transport, are pH-sensitive. Blood pH is tightly regulated by the body through mechanisms such as respiration and renal function.

When the pH of blood falls below 7.35, it is termed acidosis, which can lead to various physiological disturbances. Conversely, a pH above 7.45 is known as alkalosis, which can also cause significant health issues. Maintaining blood pH within this narrow range is critical for overall metabolic function and health.
