The main function of Henle's loop is to obtain water and sodium chloride from the urine. This activity allows urine production to be more concentrated than blood, reducing the amount of water needed for survival. WebThe kidneys contain nephrons consisting of glomeruli designed to filter the plasma, Bowman capsules that collect the filtrate, and tubules that resorb most of the filtered water and nutrients while excreting waste metabolites.
