What is the normal range of pH for human blood?

The normal range of pH for human blood is between 7.35 and 7.45, which is considered slightly alkaline. This narrow range is critical for maintaining various physiological functions and biochemical processes in the body.

The pH level of blood is a vital indicator of overall health, and deviations from this range can lead to conditions such as acidosis (when pH is below 7.35) or alkalosis (when pH is above 7.45). The body regulates pH through various mechanisms, including respiration and metabolic processes, to keep it within this optimal range.

The other ranges provided are outside the typical physiological pH for blood, with some being indicative of severe imbalances that can result in serious health issues. Understanding the normal pH range helps healthcare professionals assess a patient's acid-base status and intervene appropriately if necessary.
