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 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: -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.
