How do blood-pressure-lowering diuretics function?
What will be an ideal response?
Answer: Most act to reduce Na+ reabsorption, causing more Na+ and water to be lost in the urine, increasing urine output. However, the location of function varies. Loop diuretics block Na+ reabsorption in the ascending loop by blocking the NaKCl channel. Potassium-sparing diuretics act on the cortical collecting duct, blocking aldosterone or Na+ channels on the apical membrane. Osmotic diuretics such as mannitol are filtered but not reabsorbed. As these increase osmotic pressure in the lumen, water is retained in the lumen, increasing urine output.
