Which outcome occurs in mammals when subcutaneous arteriolar vasodilation is triggered by rising ambient temperatures?

💡 Explanation

When ambient temperature rises, subcutaneous arteriolar vasodilation increases blood flow near the skin surface because reducing vessel resistance enhances convective heat transfer. Therefore increased heat loss results, rather than reduced shivering, decreased brown fat metabolism or elevated setpoint which would counteract the need for cooling.
