← Nature & AnimalsWhich physiological response increases when vasodilation affects an animal's peripheral vessels in cold water?
A)Elevated body temperature from metabolic heating
B)Rapid oxygen depletion within muscles
C)Increased risk of paradoxical afterdrop✓
D)Reduced heat loss via convection
💡 Explanation
When vasodilation occurs in peripheral vessels during cold water immersion, heat transfer increases due to the reduced insulation, triggering a cold shock response potentially causing paradoxical afterdrop because core cooling accelerates. Therefore risk of afterdrop results, rather than elevated temperature, oxygen sparing or reduced convection which are opposite to expected processes.
