Verified step by step guidance

Understand the role of Antidiuretic Hormone (ADH) in the body. ADH is responsible for regulating water balance by increasing water reabsorption in the kidneys.

Identify the regions of the renal tubule: proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct.

Recognize that ADH primarily acts on the collecting duct of the nephron. It makes the walls of the collecting duct more permeable to water, allowing more water to be reabsorbed back into the bloodstream.

Consider the function of each part of the renal tubule: the proximal convoluted tubule reabsorbs nutrients, ions, and water; the loop of Henle concentrates urine; the distal convoluted tubule further adjusts ion and water balance; and the collecting duct is where ADH exerts its effect.

Conclude that the collecting duct is the correct target region for ADH action, as it is the site where water reabsorption is regulated in response to the hormone.
