Final answer:
The bandage provides the function of keeping bacteria out of the body, which is normally done by healthy skin.
Step-by-step explanation:
The function that is normally provided by healthy skin but is now provided by the bandage is keeping bacteria out of the body. Healthy skin acts as a physical barrier that prevents bacteria from entering the body. It has a protective layer and secretes oils and sweat that create an acidic environment, which inhibits the growth of bacteria. The bandage serves as an artificial barrier that prevents bacteria from entering the wound and causing infection.
