WebCorrect option is A) The main function of loop of Henle is the reabsorption of water from the contents of renal tubules. Fresh water fish has no loop of henle. Their bodies take on water by osmosis, therefore they rid their bodies of excess water rather than conserve it. Fresh water fish drink little water and produce large amount of urine. In the kidney, the loop of Henle (or Henle's loop, Henle loop, nephron loop or its Latin counterpart ansa nephroni) is the portion of a nephron that leads from the proximal convoluted tubule to the distal convoluted tubule. Named after its discoverer, the German anatomist Friedrich Gustav Jakob Henle, the loop of Henle's main function is to create a concentration gradient in the medulla of the kidney.
