Which physiological outcome occurs in a dog panting on a hot day via vasodilation?

💡 Explanation

When a dog pants on a hot day, the vasodilation of blood vessels in the tongue and respiratory tract promotes convective heat transfer because it increases the circulating blood volume thus carrying more heat to the surface for evaporation. Therefore increased heat dissipation results, rather than reduced flow, enhanced oxygen absorption, or decreased metabolic rate which have inverse corellations.
