If Henle's loop were absent from mammalian nephron, which one of the following is to be expected ?
Options
- Athere will be no urine formation
- Bthere will be hardly any change in the quality and quantity of urine formed
- Cthe urine will be more concentrated
- Dthe urine will be more dilute
Correct answer
D. the urine will be more dilute
Step-by-step solution
The principal function of the loop of Henle appears to be the recovery of water and sodium chloride from the urine. This function allows production of urine, that is more concentrated than blood, limiting the amount of water needed as intake for survival. Thus, if Henle's loop were absent from mammalian nephron, urine will be more dilute. Related Theory Mammalian kidneys have the loop of Henle and length of the loop in the kidney determines how concentrated the final urine is. Birds, and reptiles don't have long lo
