← Human Body & HealthWhich outcome is most likely in an individual with hypertension whose kidneys exhibit increased aldosterone production but normal angiotensin II levels?
A)Decreased sodium reabsorption in nephron
B)Elevated potassium levels in the blood
C)Increased blood volume and pressure✓
D)Reduced arterial vasoconstriction response
💡 Explanation
Increased aldosterone promotes sodium and water retention in the kidneys, because it acts on the distal tubules and collecting ducts. This increases blood volume and, therefore, blood pressure, rather than the opposite, due to a failure in the mineralocorticoid receptor regulation by other hormones.
