← Human Body & HealthWhat distinguishes angiotensin II's vasoconstrictive effect in chronic hypertension from its role in acute blood pressure regulation?
A)Potentiates baroreceptor reflex sensitivity acutely
B)Induces arterial remodeling, increasing stiffness✓
C)Primarily stimulates aldosterone release rapidly
D)Inhibits nitric oxide synthase transiently
💡 Explanation
Chronic hypertension involves arterial remodeling due to sustained angiotensin II activity, increasing vascular stiffness because angiotensin II stimulates collagen and elastin deposition. Therefore, arterial stiffness becomes a long-term consequence, rather than acute vasoconstriction; other mechanisms regulate immediate blood pressure.
