What is the normal pH range for blood?

The normal pH range for blood is recognized as 7.35 to 7.45. This range is critical for maintaining homeostasis, as even slight deviations can lead to significant physiological consequences. A pH lower than 7.35 indicates acidosis, where the blood is too acidic, and a pH higher than 7.45 indicates alkalosis, where the blood becomes too alkaline. Both conditions can disrupt various bodily functions, including the activity of enzymes and the transport of oxygen. Hence, a pH within the range of 7.35 to 7.45 is essential for optimal health and metabolic processes in the body. Maintaining this balance is a key aspect of respiratory and renal function, which regulate acid-base levels.
