← Nature & AnimalsWhich mechanism causes reduced kidney filtration during mammalian hibernation induced by hypothermia?
A)Vasoconstriction lowers glomerular pressure✓
B)Increased renin secretion elevates pressure
C)Lowered ADH increases fluid reabsorption
D)Reduced ANP increases sodium filtration
💡 Explanation
When hypothermia induces hibernation, vasoconstriction reduces blood flow to the kidneys, reducing glomerular hydrostatic pressure because the body prioritizes core temperature maintenance curtailing non-essential functions. Therefore reduced filtration happens rather than elevated pressure or altered hormone effects, which would counteract the overall hibernation response.
