question 35

Multiple Choice

How does the renal countercurrent multiplier mechanism allow the creation of a concentrated urine?

• A)It transports NaCl from the medullary interstitial fluid into the collecting duct,which directly increases the osmolarity of the urine.
• B)It transports urea from the medullary interstitial fluid into the collecting duct,which directly increases the osmolarity of the urine.
• C)By concentrating NaCl in the renal medullary interstitial fluid,it allows water to be reabsorbed from the collecting ducts when vasopressin is present.
• D)By pumping NaCl and urea into the ascending limb of the loop of Henle,it raises the solute load,which turns into a concentrated urine once water is extracted from the collecting duct.
• E)When anti-diuretic hormone is present,it stimulates the pumping of NaCl from the medullary interstitial fluid and water follows,concentrating the urine.
