WebADH acts on the kidneys to increase water reabsorption and decrease urine output, thus helping to maintain fluid and electrolyte balance in the body. ... When plasma calcium levels drop too low, the parathyroid glands secrete PTH, which acts on the bones, kidneys, and intestines to increase calcium levels in the blood. PTH stimulates the ... WebThiazide diuretics also increase calcium reabsorption at the distal tubule. By lowering the sodium concentration in the tubule epithelial cells, thiazides indirectly increase the activity of the basolateral Na + /Ca 2+ antiporter to maintain intracellular Na + level, facilitating Ca 2+ to leave the epithelial cells into the renal interstitium.
