WebThe rest of the kidney tubule (the loop of Henle, the second coiled tubule and the collecting duct) is designed to reabsorb some of the remaining water as necessary. The remaining fluid, called urine, passes down the collecting duct to the pelvis of the kidney and then onto the bladder (via the ureter) where it is temporarily stored. WebThe Loop of Henle is an important part of the kidney nephron in forming concentrated urine. It is a long loop, which forms something known as a hairpin countercurrent mechanism. It is called countercurrent because the direction of flow in the descending loop is in the opposite direction to the flow in the ascending loop. tasheni followershttp://www.ib.bioninja.com.au/higher-level/topic-11-animal-physiology/113-the-kidney-and-osmoregu/osmoregulation.html tasheonna lewis
