What is the normal pH level of blood in the human body?

The normal pH level of blood in the human body falls within the range of 7.35 to 7.45. This slightly alkaline range is crucial for maintaining metabolic processes and overall physiological function. Variations outside this range can indicate acidosis (pH less than 7.35) or alkalosis (pH greater than 7.45), which can have significant health implications. The body employs various homeostatic mechanisms, such as respiration and renal function, to regulate blood pH within this narrow range, emphasizing the importance of maintaining it for optimal health and function. Understanding this range is essential for recognizing potential medical conditions that arise from pH imbalances.
