WebHenle's loop is a long U-shaped part of the tubule that carries urine inside each nephron of reptiles, birds, and mammals. 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.
