Renal System
What is the effect on the kidney caused by increasing the release of ADH?
The collecting duct becomes more permeable to water.
The ascending limb of the loop of Henle becomes impermeable to water.
The descending limb of the loop of Henle becomes permeable to water.
The collecting duct becomes impermeable to water.
The collecting duct becomes more permeable to water.
Antidiuretic hormone prevents diuresis (decreases urine formation) by causing more water to be reabsorbed from the filtrate as it passes through the collecting duct.
