Quizplus · Accepted Answer

All of the choices listed contribute to maintaining a high solute concentration in the kidney medulla. High urea concentration in the medulla, active transport of solutes from the ascending limb of the loop of Henle, the vasa recta's counter-current exchange mechanism, and the overall functions of the loop of Henle work together to concentrate urine and regulate water and solute balance in the body.
