Multiple Choice

Which of the following statements about the collecting duct in the presence of antidiuretic hormone (ADH) is correct?

The collecting duct becomes permeable to water, allowing water reabsorption.

The collecting duct remains impermeable to water, preventing water reabsorption.

ADH has no effect on the permeability of the collecting duct.

ADH causes the collecting duct to secrete water into the filtrate.

Verified step by step guidance

Understand the role of antidiuretic hormone (ADH): ADH is a hormone secreted by the posterior pituitary gland that regulates water balance in the body by affecting the kidneys.

Focus on the collecting duct: The collecting duct is a structure in the nephron of the kidney that plays a key role in water reabsorption and urine concentration.

Learn how ADH affects the collecting duct: ADH increases the permeability of the collecting duct to water by promoting the insertion of aquaporins (water channels) into the membrane of the duct's cells.

Consider the physiological outcome: When the collecting duct becomes permeable to water due to ADH, water is reabsorbed into the bloodstream, concentrating the urine and reducing water loss.

Eliminate incorrect options: Based on the mechanism of ADH, rule out statements that suggest the collecting duct remains impermeable to water, secretes water, or is unaffected by ADH.
