Chapter 1 The nephron and fluid balance Learning goal: Explain how the kidney regulates water and electrolytes. Functional parts of the nephron Glomerulus Filters plasma; GFR measures this.; PCT Reabsorbs ~65% of sodium, water, glucose.; Loop of Henle Concentrates urine; loop diuretics act here.; DCT Thiazides act here; calcium reabsorption.; Collecting duct ADH and aldosterone fine-tune water and sodium.; Simplified teaching schematic - not to anatomical scale.
