Detailed explanation-1: -The principal function of the loop of Henle is in the recovery of water and sodium chloride from urine. This function allows production of urine that is far more concentrated than blood, limiting the amount of water needed as intake for survival.
Detailed explanation-2: -This part of the nephron is called the loop of Henle. Its main function is to reabsorb water and sodium chloride from the filtrate. This conserves water for the organism, producing highly concentrated urine.
Detailed explanation-3: -The loop of henle is a region of the kidney’s nephrons which through active and passive transport of Na+ and Cl-ions lowers the water potential of the kidney’s medulla, allowing greater reabsorbtion of water into the blood at both the loop of henle and collecting duct.
Detailed explanation-4: -The main function of Henle’s loop is to reabsorb water and important nutrients in the filtrate. Through the counter-current mechanism, it aims to reduce the volume of water and solutes within the urine without any change in its concentration.
Detailed explanation-5: -If the ascending limb of the loop of Henle were permeable to water, this process would be impossible and the filtrate would not be concentrated in the collecting duct.
