Which outcome occurs when a mammal experiences sustained vasodilation to counteract hyperthermia?

💡 Explanation

When vasodilation continues to counteract external heat, increased blood flow to the skin occurs because of peripheral blood vessel widening, reducing systemic blood pressure, sometimes leading to syncope. Therefore deceased blood pressure results, rather than metabolic increases, elevated setpoint, or reduced shivering, which each operate with different mechanisms.
