Which of the following is the diluting segment of kidney?
(A) PCT (B) Collecting duct (C) Ascending thick loop Henle (D) Descending loop of Henle
(C) Structure Function Glomerulus PCA Descending limb of loop of henle Ascending limb of loop of henle DCT Collecting duct Isotonic ultrafiltration Reabsorption of Na+ H2O, amino acids, HCO3,K+, Ca2+, Cl- Reabsorbs H2O into interstitium, impermeable to solute. Impermeable to H2O,loop diuretics acts here. Resorption of Na, K, Cl, k/a the diluting segment. Thiazide diuretics act here, removes 10% of Na+& Cl-, some H2O also removed. Aka concentrating segment, absorbs 10 - 12% of H2O under ADH, principle cells reabsorbs Na+& secretes K+ , intercalated cells reabsorbs K+ & secretes HCO-3.
