An Unbiased View of phosphate buffer system
This is true for hydrogen ions and bicarbonate. If bicarbonate is reabsorbed and/or acid is secreted in the urine, the pH gets to be more alkaline (will increase). When bicarbonate is not really reabsorbed or acid just isn't excreted into the urine, pH becomes much more acidic (decreases). The metabolic compensation through the renal system takes
