Question

Quizplus · Accepted Answer

As the tubular fluid flows up the ascending loop of Henle, there is active transport of ions (Na+, K+, Cl-) out of the tubular fluid into the surrounding interstitial fluid. This leads to a decrease in the concentration of ions in the tubular fluid, resulting in a decrease in overall concentration.
