Question

As filtrate moves through the ______________in mammals, it generally undergoes a dramatic decrease in osmolarity.

Answer 1

As filtrate moves through the Ascending segment of the loop of Henle in mammals, it generally undergoes a dramatic decrease in osmolarity.

The ascending limb of the loop of henle is direct continuation from descending limb of henle, one of the structure in the nephron of the kidney.This segment  of ascending limb has thin and thick segment.

The descending loop leads to sharp bend, in which ascending loop continues.This loop has thin and thick portion. Thick ascending limb is called distal straight tube. Thin-segment is permeable to ions and impermeable water.25% of sodium and potassium is absorb by the wall of ascending limb of the loop of henle.
