Phosphoric acid buffer system in the blood
WebProper physiological functioning depends on a very tight balance between the concentrations of acids and bases in the blood. Acid-balance balance is measured using the pH scale, as shown in Figure 26.15. A variety of buffering systems permits blood and other bodily fluids to maintain a narrow pH range, even in the face of perturbations. WebPhosphate is the most predominant urine buffer; its urinary excretion increases with acidosis. The mechanisms probably involve a decrease in the preferentially transported species, HPO4 (2-), and a direct effect of pH on proximal tubule apical phosphate transport.
