PH value of human blood

The pH value of human blood, also known as the hydrogen ion concentration index, is a scale of the hydrogen ion activity in the solution, which is also a measure of the acidity and alkalinity of the solution in the usual sense. This concept was proposed by Danish biochemist Søren Peter Lauritz Sørensen in 1909. P stands for potenz in German, meaning strength or concentration, and H stands for hydrogen ion (H+). Sometimes pH is also written as pondus hydrogenii in Latin form. Normally, the pH value is a number between 0 and 14, when the pH<7, the solution is acidic, when the pH>When the pH is 7, the solution is alkaline, and when the pH is 7, the solution is neutral. The pH value of human blood is 7.34 - 7.45. Our blood is slightly alkaline under normal conditions, and because the body has the ability to automatically adjust the acid-base, it will not change greatly even under special circumstances. The blood of a healthy person is generally around pH7.35 (pH7 is neutral, above 7 is alkaline, below 7 is acidic), even if there is a change, it is just a difference in the second digit below the decimal point. However, of course people are fatigued due to labor, and 'fatigue' is a physiological phenomenon, and it can also be said to be a phenomenon in which the metabolites produced by the burning of substances in the body increase; this 'metabolite' is a kind of 'acid' (called acid). Lactic acid and pyroglucanic acid), this kind of acid increases, of course, the blood tends to become acidic, that is, the number of pH decreases, and acidic blood is harmful to the body and can cause various diseases. In other words, fatigue is the phenomenon that the blood tends to be acidic, and 'fatigue' is the return of the blood to its original state of being slightly alkaline. Whether a person can quickly restore the blood to slightly alkaline after fatigue depends on the strength of the body's ability to regulate acid-base; diabetics often suffer from fatigue: the body's ability to regulate acid-base is too weak, and the blood tends to be acidic. Therefore, our body always reserves sufficient regulating ability, so that the blood is not prone to acidity, and even if it has this tendency, it can be recovered immediately. The main role in regulating acid-base in the body is 'calcium wanderer'. In layman's terms, if calcium is sufficient in our body, the ability to regulate acid-base is strong.
