← Human Body & HealthWhich outcome reduces urine volume due to elevated vasopressin?
A)Increased aquaporin water channel expression✓
B)Decreased sodium reabsorption in tubules
C)Reduced glomerular filtration rate
D)Elevated potassium excretion levels
💡 Explanation
Elevated vasopressin promotes water reabsorption via increased aquaporins via osmosis; therefore, urine volume decreases because water moves back into the blood, rather than sodium reabsorption changing, affecting just sodium balance.
