← Human Body & HealthWhich kidney function outcome is compromised during water deprivation?
A)Sodium reabsorption increases in distal tubule
B)Osmosis decreases in collecting duct✓
C)Potassium secretion activates in nephron
D)Filtration rate decreases at glomerulus
💡 Explanation
Water deprivation inhibits osmoregulation; osmosis decreases, reducing water reabsorption in the collecting duct because the osmotic gradient is not as strong near the loop of Henle. Therefore, dehydration worsens, rather than compensatory mechanisms activating.
