The H + ion concentration of the body fluids is kept constant within a very narrow range so that the biochemical processes of the metabolism and the electrophysiological processes in the excitable membranes can take place undisturbed. The concentration equilibrium of the H + ions is endangered by the non-volatile or metabolic acids that constantly arise in the metabolism and the volatile carbon dioxide resulting from the oxidative combustion of carbohydrates and fats. Significant deviations in the H + ion concentration would impair the function of the organs and, in extreme cases, bring it to a standstill. This is why regulation systems ensure that the H + ion concentration or the pH value changes only slightly under the influence of the acids and bases that are formed in the organism.
