← Nature & AnimalsWhich outcome occurs in response to overheating if a mammal requires maximal dissipation of metabolic heat?
A)Cutaneous vasodilation causes heat loss✓
B)Reduced shivering thermogenesis occurs
C)Brown fat metabolism gets upregulated
D)Non-shivering thermogenesis increases overall
💡 Explanation
Increased blood flow towards the skin's surface via cutaneous vasodilation enables radiative and convective heat loss, because this mechanism leverages thermal gradients to dissipate energy; therefore, overheating is countered by increased blood flow, rather than by retaining this energy.
