Which thermal consequence results from cutaneous vasodilation during mammalian brown adipose tissue activation?

💡 Explanation

During brown adipose tissue activation, cutaneous vasodilation occurs because sympathetic nervous system stimulates smooth muscle relaxation in blood vessels, increasing peripheral blood flow and thus boosting peripheral oxygen delivery. Therefore increased oxygen delivery results, rather than heat conservation, reduced metabolism, or intensified frostbite risk because only vasodilation increases peripheral circulation.
