← Nature & AnimalsWhich physiological effect occurs when a mammal experiences vasodilation in response to localized environmental heating?
A)Increased convective heat loss to surroundings✓
B)Reduced metabolic heat generation
C)Enhanced shivering thermogenesis
D)Decreased piloerection in skin
💡 Explanation
When localized heating triggers vasodilation, increased blood flow to the skin surface occurs due to relaxation of smooth muscles in blood vessels, resulting in higher skin temperature and subsequently, higher convective heat loss. Therefore increased convective heat loss to surroundings results, rather than reduced heat generation, shivering, or decreased piloerection, which have opposing thermal contexts.
