If a patient exhibits severe dehydration with elevated plasma osmolality and decreased blood pressure, which consequence directly results from increased aquaporin expression in the collecting ducts?

💡 Explanation

Increased aquaporin expression enhances the permeability of the collecting ducts to water because it facilitates water movement down the osmotic gradient. Therefore, more water is reabsorbed into the bloodstream, rather than being excreted in urine, which helps restore blood volume and reduce plasma osmolality.
