Which physiological outcome occurs when a mammal experiences prolonged exposure to high ambient temperatures influencing thermoregulation?

💡 Explanation

When mammals experience high ambient temperatures, vasodilation occurs because heat stress triggers widening of blood vessels near the skin surface to increase convective heat transfer. Therefore enhanced vasodilation increases cutaneous blood flow, rather than vasoconstriction, elevated metabolic rate or suppressed shivering because these mechanisms either conserve or generate heat.
