WebbRegulation of. acid-base. balance. The cells of the body derive energy from oxidative processes that produce acidic waste products. Acids are substances that ionize to yield free protons, or hydrogen ions.

Although the lung's ability to expel CO 2 and the kidney’s ability to excrete or absorb hydrogen ions allow close regulation of pH, their responses alone are not sufficient to prevent immediate local changes in pH at the tissue. This is the role of the buffering systems. Buffering systems are chemicals within ...

WebbThe proximal tubule is the primary site for ammoniagenesis, but there is evidence for ammoniagenesis by most renal epithelial cells. Ammonia produced in the kidney is either excreted into the urine or returned to the systemic circulation through the renal veins. WebbMost of this ammonium NH4+ is lost in the urine, which helps the kidneys get rid of a large amount of hydrogen H+. A second buffer system uses phosphate. Monohydrogen phosphate HPO42- enters the tubule from the plasma. It is poorly reabsorbed from the tubules, so it concentrates there.

WebbAs with any buffer system, the pH is balanced by the presence of both a weak acid (for example, H 2 CO 3) and its conjugate base (for example, HCO − 3) so that any excess acid or base introduced to the system is neutralized.. Failure of this system to function properly results in acid-base imbalance, such as acidemia (pH < 7.35) and alkalemia (pH > 7.45) … Webbto be excreted into the urine, there must be two com-ponents to the nephron’s task: reabsorption of ﬁltered bicarbonate, and addition of net acid to the tubular ﬂuid. …
