Loop diuretics promote diuresis by - decreasing the osmolarity of the renal medulla inhibiting an enzymatic reaction blocking aldosterone receptors O increasing urine osmolarity

4,   H+ secretion in the renal tubule happens by   Multiple Choice   It follows a negative ion like Cl- or PO43-   H+/HCO3- exchanger in the basolateral membrane   Na+/H+ exchanger in the apical membrane   It first combines with HCO3- and is then regenerated in the tubular fluid

water movement in and out cells is due mainly to fluctuation of the na+ and k+ ion concentrations

The loop of Henle in the mammalian renal tubule…
