Which outcome is directly promoted by vasodilation in a mammal initiating exercise and increasing metabolic rate?

💡 Explanation

When metabolic rate increases during exercise initiation, vasodilation occurs because smooth muscle cells in blood vessel walls relax, increasing blood flow near the skin and promoting conduction heat transfer. Therefore enhanced heat dissipation results, rather than affecting shivers, liver function, or direct oxygen delivery which all have different regulatory mechanisms.
