An individual's blood pressure consistently rises despite dietary changes. Which mechanism most likely explains why the ACE inhibitor drug, captopril, effectively reduces blood pressure in this scenario?

💡 Explanation

Captopril inhibits angiotensin-converting enzyme (ACE), therefore angiotensin II production decreases. Angiotensin II is a potent vasoconstrictor; because its production is reduced, vessel constriction is minimized, rather than other mechanisms directly affecting sodium or sympathetic activity.
