Detailed explanation-1: -The descending limb of Henle’s loop is permeable to water but impermeable to electrolytes.
Detailed explanation-2: -The descending loop contains AQP1 and is therefore permeable to water but impermeable to salt. As urine descends into the medulla, the high interstitial solute concentration osmotically draws water from the descending limb and concentrates salt within the lumen.
Detailed explanation-3: -The descending limb of the loop of Henle forms the initial part of the loop of Henle which helps in maintaining the urine concentration. It is entirely impermeable to the sodium and chloride ions but it is permeable to the water which accounts for reabsorption of water from this tubule through osmosis.
Detailed explanation-4: -Within the nephron of the kidney, the descending limb of loop of Henle is the portion of the renal tubule constituting the first part of the loop of Henle. Scheme of renal tubule and its vascular supply.
Detailed explanation-5: -Final answer: Descending limb of the loop of Henle is impermeable to salts.
