← Human Body & HealthWhy does the body undergo peripheral vasoconstriction when exposed to a cold environment, despite the increased risk of localized tissue damage?
A)To minimize metabolic heat production
B)To maximize heat loss via radiation
C)To prioritize core temperature maintenance✓
D)To promote sweating and evaporative cooling
💡 Explanation
The body prioritizes maintaining the core temperature via vasoconstriction, reducing blood flow to extremities because the hypothalamus's set point must be defended. Therefore, core survival is favored, rather than preserving peripheral tissue integrity, which faces potential cold injury.
