← Human Body & HealthWhy does scar tissue have reduced function compared to normal skin during thermoregulation?
A)Keratinocyte density prevents heat loss
B)Increased melanocytes absorb excessive radiation
C)Collagen fibers lack sweat glands✓
D)Sebum production inhibits vasodilation nearby
💡 Explanation
Scar tissue contains primarily collagen fibers which, because of their rapid deposition during wound healing, lack the sweat glands and hair follicles present in normal skin; therefore, evaporative cooling is impaired in scar tissue rather than enhanced by keratinocytes or melanocytes.
