Question

Quizplus · Accepted Answer

Juxtamedullary nephrons are specialized nephrons found only in mammals that live in arid or semi-arid environments. These nephrons are important for water conservation, as they allow for the production of concentrated urine. Wetland mammals, on the other hand, do not need to conserve water in the same way, so they do not have as many juxtamedullary nephrons.

Therefore, having more juxtamedullary nephrons in mammals of arid regions enhances water conservation.
