Quizplus · Accepted Answer

Juxtamedullary nephrons have long loops of Henle that extend deep into the medulla of the kidney, allowing for the establishment of the concentration gradient necessary for water conservation and the production of concentrated urine. Cortical nephrons do not have long loops of Henle and, therefore, do not contribute as significantly to these functions.
