What is the primary site of action for loop diuretics within the nephron?

  1. Proximal convoluted tubule
  2. Thin descending limb of the loop of Henle
  3. Thick ascending limb of the loop of Henle
  4. Distal convoluted tubule
Show answer and explanation

Correct answer: Thick ascending limb of the loop of Henle

The thick ascending limb is the 'diluting segment' of the nephron and possesses high metabolic activity. Loop diuretics target the NKCC2 transporters located specifically on the luminal membrane of cells in this segment.
