Which outcome accelerates heat loss from elephant ears when blood vessels dilate?

💡 Explanation

When blood vessels in elephant ears dilate, vasodilation increases blood flow to the surface because more heat gets carried to increased area enhancing convective and radiative heat transfer. Therefore convective and radiative heat loss is accelerated, rather than decreased metabolic generation, enhanced evaporative cooling, or reduced dermal insulation which don't directly result from increased dermal blood flow.
