Your answer: ADH has the greater effect on urine volume. The urine volume drastically decreases from the baseline value of 201 ml to 16 ml whenever ADH was added. This is because ADH increases the amount of water reabsorbed in the distal tubule, thus decreasing the urine volume.

Does ADH favor the formation of a dilute or concentrated urine?

How does ADH affect the urine volume? ADH favor the formation of concentrated urine. It causes an increase of water permeability in the Distal tubule and collecting ducts.

What will happen to the urine volume compared with baseline when ADH is added to the collecting duct?

What will happen to the urine volume (compared with baseline) when ADH is added to the collecting duct? Urine volume will decrease dramatically.
