The loop of Henle, and two you got wrong yesterday.
Yes, all 7,000 of them!
Upload a chapter in Spanish and the questions come back in Spanish. This is about the language your document is written in — Reteva’s own screens are in English.
Nothing asks you to take its word for it. The passage the question was written from comes with the answer, and the page number tells you where to find it in your own file.
The question
Why does the thick ascending limb not reabsorb water?
The answer
It has no water channels in its membrane
Why
Salt is pumped out of it without water following, which is what leaves the fluid dilute and the surrounding tissue salty.
Your document, page 12
The thick ascending limb actively transports sodium and chloride out of the tubule. Because this segment lacks aquaporins, water cannot follow the solute, so the tubular fluid becomes progressively more dilute while the medullary interstitium becomes progressively more concentrated.
