Question

Desert animals have a long loop of Henle

• A. There will be no urine formation
• B. There will be hardly any change in the quality of urine formed
• C. The urine will be more concentrated
• D. The urine will be more dilute

Answer 1

The correct option is C

The urine will be more concentrated

Kidneys of desert animals have longer loops of Henle to make the animals' urine as concentrated as possible. The principal function of the loop of Henle appears to be the recovery of water and sodium chloride from the urine. This helps desert animals live for long periods of time on minimal amounts of water.
