What is the function of the ascending loop of Henle?
A
It provides water for reabsorption by the interstitial fluid and capillaries.
B
It loses urea to the renal medulla, helping this tissue to maintain its concentration gradient of solutes.
C
It absorbs some drugs and poisons from surrounding capillaries.
D
It collects processed filtrate from the nephrons.
E
It helps maintain the concentration gradient of NaCl in the interstitial fluid, thus increasing water reabsorption.
Verified step by step guidance1
Understand the structure of the nephron, which includes the loop of Henle. The loop of Henle is divided into two parts: the descending limb and the ascending limb.
Recognize the function of the ascending loop of Henle. It is impermeable to water but actively transports NaCl out of the filtrate into the surrounding interstitial fluid.
Explain how the active transport of NaCl from the ascending loop of Henle contributes to the concentration gradient in the renal medulla. This gradient is crucial for the kidney's ability to concentrate urine.
Discuss the role of the concentration gradient in water reabsorption. The gradient created by the ascending loop of Henle allows water to be reabsorbed from the collecting duct, which is permeable to water.
Summarize the importance of the ascending loop of Henle in maintaining the concentration gradient of NaCl in the interstitial fluid, which ultimately aids in the kidney's ability to conserve water and produce concentrated urine.
