What are sites of action of diuretics?

5 main classes: Loop (act on ascending Henle's Loop) Thiazide (act on distal convoluted tubule) Carbonic-Anhydrase Inhibitors (on proximal convoluted tubule) Potassium-Sparring Diuretics (Cortical collecting tubule aldosterone sensitive principal cells [aldosterone antagonists and Na+ channel blockers]) Osmotic Diuretics (proximal convoluted tubules and descending henle's loop)
