Bah, exam language! It's a clever trick the kidney uses—like my sewing machine's reverse stitch—to pull water back and save it, so urine gets concentrated. I memorized that diagram perfectly, yaar. But now I see Papa's swollen feet, the doctor saying "kidneys weak," and I regret not understanding that when this loop's mechanism fails, the body cannot hold onto water... just like our savings couldn't hold.
