What substance regulates the permeability of the collecting ducts?

Question

Quizplus · Accepted Answer

ADH is the antidiuretic hormone that regulates the permeability of the collecting ducts in the kidneys. ADH helps the body conserve water by increasing the reabsorption of water from the urine back into the bloodstream. When the body is dehydrated, ADH levels increase, causing the collecting ducts to become more permeable to water, resulting in concentrated urine. Conversely, when the body has an excess of water, ADH levels decrease, causing the collecting ducts to become less permeable to water, resulting in dilute urine.
