Potassium concentration is regulated throughout the tubules with aldosterone being the strongest influence for loss. Renin activates angiotensinogen, which becomes angiotensin I. Antidiuretic hormone is produced by the hypothalamus and stored in the posterior pituitary gland and is important in maintaining fluid balance. Carbonic anhydrase causes sodium ions to be reabsorbed and allows carbon dioxide and water to combine to form carbonic acid. This leads to the formation of sodium bicarbonate, which is stored in the renal tubules as the body's reserve for use when the body needs a buffer against acid.
