Fat present below the skin surface in our body acts as a barrier against:
- Loss of heat from the body
- Loss of essential body fluids
- Loss of salts from the body
- Entry of harmful micro-organisms from the environment
Explanation
Option (a) is correct
- Subcutaneous fat acts as an insulator. It reduces heat loss and helps maintain body temperature. It does not prevent fluid or salt loss, nor is it the primary barrier against microorganisms (skin performs that function).
