← Human Body & HealthA burn patient with extensive skin damage experiences increased susceptibility to bacterial infections. Which mechanism explains why this occurs in the compromised integumentary system?
A)Decreased melanocyte activity reduces UV protection
B)Increased keratinocyte proliferation depletes nutrient reserves
C)Disrupted epidermal barrier allows pathogen entry✓
D)Elevated sebum production promotes microbial growth
💡 Explanation
Skin barrier function protects against external threats. Disruption of the epidermal barrier permits direct bacterial invasion because the physical blockade is compromised. Therefore, option C is correct, rather than the other options related to UV protection, nutrient depletion, or increased microbial food sources that do not directly address barrier failure.
