Which physiological outcome reduces oxygen extraction efficiency when a mammal with peripheral vasoconstriction rapidly enters a warmer environment?

💡 Explanation

When an animal with vasoconstriction enters a warmer environment, rapid peripheral vasodilation occurs because the body attempts to dissipate heat, causing blood to flow rapidly without adequate oxygen extraction by tissues, leading to increased core temp. Therefore, elevated core temperature results, instead of increased respiration, reduced viscosity, or impaired hemoglobin affinity, each requiring distinct biochemical changes.
