An animal's capacity to conserve water and to concentrate solutes for excretion in the urine is greater in a kidney with longer
A) Bowman's capsules
B) loops of Henle
C) proximal tubules
D) ureters
E) afferent arterioles

Question

Quizplus · Accepted Answer

The loops of Henle, located in the renal medulla, are responsible for creating a concentration gradient that allows for water reabsorption and concentration of solutes in the urine. The longer the loops of Henle, the greater the gradient that can be created, allowing for more efficient water conservation and solute concentration. The other structures listed do not play as crucial of a role in this process.
