Desert Kangaroo Conditions Henle Mammals Longer Water Rat

The flashcard explains that the long loops of Henle in the desert kangaroo rat's kidneys help maintain a steep water potential (WP) gradient, allowing water to move out of capillaries, thus aiding in water conservation.

La scheda spiega che i lunghi anelli di Henle nei reni del ratto canguro del deserto aiutano a mantenere un gradiente di potenziale idrico ripido, consentendo all'acqua di muoversi attraverso le pareti dei capillari, contribuendo così alla conservazione dell'acqua.

Front The desert kangaroo rat, Dipodomys deserti, lives in dry and hot conditions. It excretes a very
small volume of urine relative to its size.
The loops of Henle in the kidneys of these mammals are longer than those found in mammals
of a similar size that do not live in desert conditions.
Explain how the longer loop of Henle is able to assist the desert kangaroo rat in preventing
excessive water loss.
