Question

The Henle’s loop of nephron is mainly responsible for reabsorption of water in the
kidney. Which of the following has a long loop of Henle in its nephrons to conserve
water?
i) polar bear ii) camel iii) frog iv) whale

Answer 1

Camel has a long loop of Henle in its nephrons to conserve water.

The nephrons of camels are equipped with number of juxtamedullary nephron in very high amount along with a well-developed Henle’s loop.

The amount of juxtamedullary nephrons is around 35% which is much more than in human beings 15%. The Henle’s loop of juxtamedullary nephrons along with counter flowing blood vessels, which is called vasa recta, assist in conservation of water.
