Describe the response the kidneys have to dehydration and excessive water intake. What happens to the concentration of urine in

each case ?
Biology

leonid [27]3 years ago
6 0

during dehydration the concentration of urine is increased and the volume of it is decreased. Because kidneys want to retain and reabsorb as much water as possible back into the blood.

Excessive water intake causes less concentrated urine with increased volume. The kidneys don’t reabsorb that much water because there is enough of it in the plasma.
