Answer
Dilute urine is produced by the combined effects of reabsorption of more solutes than water at the following sites:
The ascending limb of the nephron loop
The distal convoluted tubule (DCT)
The collecting duct (CT).
Work Step by Step
The kidneys are able to regulate water loss in urine. They produce a large volume of dilute urine when fluid intake is high, and they produce a small amount of concentrated urine when fluid intake is low.
In the absence of ADH, urine is very dilute.
