Which outcome results when a hibernating mammal experiences external warming, triggering peripheral vasodilation?

💡 Explanation

When a hibernating mammal warms externally, peripheral vasodilation occurs because the hypothalamus detects increased skin temperature, causing blood vessels in extremities to widen, leading to blood pooling and a drop in central blood pressure. Therefore decreased cardiac output results, rather than increased metabolic rate, reduced oxygen consumption or elevated body temperature which require different triggering stimuli.
