← Human Body & HealthWhy does inhibiting aldosterone synthesis reduce blood pressure in hypertension, even when angiotensin II levels remain high?
A)It enhances baroreceptor sensitivity directly.
B)It decreases peripheral arterial stiffness.
C)It limits sodium reabsorption and volume expansion.✓
D)It blocks angiotensin-converting enzyme activity.
💡 Explanation
Inhibiting aldosterone synthesis reduces blood pressure because it directly limits sodium reabsorption in the kidneys, preventing fluid retention and subsequent blood volume expansion. Therefore, blood pressure decreases, rather than changes in arterial stiffness or direct baroreceptor modulation.
