Question

Quizplus · Accepted Answer

The collecting ducts and distal convoluted tubules vary in their permeability to water relative to the amounts of antidiuretic hormone (ADH) present. When ADH levels are low, the tubules are impermeable to water and little water is reabsorbed, leading to the production of dilute urine. When ADH levels are high, the tubules become permeable to water and more water is reabsorbed, leading to the production of concentrated urine. None of the other options are correct.
