What is generally considered a normal blood pH range in humans?

The normal blood pH range in humans is typically between 7.35 and 7.45. This range is crucial for maintaining homeostasis in the body, as even slight deviations can lead to significant physiological problems. Blood pH within this range ensures that enzymes and biochemical processes function optimally, which is essential for maintaining various bodily functions.

A pH value lower than 7.35 indicates acidosis, which can result in symptoms such as confusion, fatigue, and shortness of breath. Conversely, a pH higher than 7.45 indicates alkalosis, which may lead to symptoms like muscle twitching, hand tremors, and disturbances in heart rhythm. Thus, maintaining blood pH within this range is vital for overall health and proper functioning of physiologic processes.
