WebLoop diuretics. The main site of sodium reabsorption is in the thick ascending limb of the loop of Henle. Here, sodium ions are actively transported out of the tubule by the membrane transport protein sodium-potassium-chloride (Na + /K + /2Cl –) cotransporter. Loop diuretics (e.g. furosemide, bumetanide and torasemide) compete with chloride ions on this … WebIn the renal medulla, the loop makes a sharp, almost 180-degree turn back toward the renal cortex as the ascending limb of the nephron loop. The ascending limb is continuous with the distal convoluted tubule. The ascending and descending limbs of the nephron loop have two distinct parts: a thin section of the limb and a thick section of the limb. north bay trade show north bay to toronto flights
