As glomerular filtrate moves through the ascending loop of Henle, the filtrate becomes more dilute. Why?
|
|
the ascending loop of Henle is permeable to water and ions
|
|
|
the ascending loop of Henle is permeable to ions but impermeable to water
|
|
|
the ascending loop of Henle is impermeable to water and ions
|
|
|
the ascending loop of Henle is permeable to water but not to ions
|
Explanation:
Detailed explanation-1: -The ascending limb of Henle’s loop is impermeable to water but permeable to electrolytes. As a result, the filtrate gets diluted as it moves up the ascending limb of Henle’s loop.
Detailed explanation-2: -Explanation: As the nephron dips into the medulla in the descending limb of the loop of Henle, water passively diffuses out of the filtrate. This concentrates the solutes in the filtrate.
Detailed explanation-3: -This part of the nephron is called the loop of Henle. Its main function is to reabsorb water and sodium chloride from the filtrate. This conserves water for the organism, producing highly concentrated urine.
