What happens to the concentration of tubular fluid as it flows up the ascending loop of Henle?
A)Its concentration remains unchanged.
B)Its concentration increases.
C) Its concentration decreases.

Question

Quizplus · Accepted Answer

As the tubular fluid flows up the ascending loop of Henle, ions such as sodium and chloride are actively transported out of the tubular fluid and into the interstitial fluid. This results in a decreased concentration of ions in the tubular fluid, leading to a dilution of the fluid. Therefore, the concentration of tubular fluid decreases as it flows up the ascending loop of Henle.
