WebAcid is actively excreted into the proximal and distal tubules where it combines with urinary buffers—primarily freely filtered phosphate (HPO 4 −2), creatinine, uric acid, and ammonia—to be transported outside the body.The ammonia buffering system is especially important because other buffers are filtered in fixed concentrations and can be depleted … WebAn acid, such as lactic acid or sulfuric acid, that accumulates in the body as a result of digestion, disease, or metabolism. It cannot be excreted from the body by ventilation but …
WebAs carbonic acid dissociates, H+ are buffered by hemoglobin proteins. At the lungs, the reaction sequence is reverse and CO2 diffuses into alveoli for exhalation. What is the protein buffer system? WebYes, the pH of the blood is controlled by the bicarbonate buffer system: CO₂ (g) + H₂O (l) ⇌ H₂CO₃ (aq) ⇌ H⁺ (aq) + HCO₃⁻ (aq) If the concentration of CO₂ temporarily gets too high, …
