Explanation:
Detailed explanation-1: -In the absence of pathological states, the pH of the human body ranges between 7.35 to 7.45, with the average at 7.40. Why this number?
Detailed explanation-2: -The alpha-stat theory of acid-base management interprets the normal value of arterial pH, usually thought of as being 7.40, as a value derived from the intracellular pH, which is close to neutrality.
Detailed explanation-3: -A blood pH imbalance can lead to two conditions: acidosis and alkalosis. Acidosis refers to having blood that’s too acidic, or a blood pH of less than 7.35. Alkalosis refers to having blood that’s too basic, or a blood pH of higher than 7.45.
