Which term describes a localized reaction with redness and swelling due to injury or infection?

• A. Abscess
• B. Inflammation
• C. Bandage
• D. Infection

Answer: (B)

Inflammation is the body's localized defensive response to tissue injury or infection. When tissue is damaged or pathogens are present, chemical signals cause nearby blood vessels to widen and become more permeable. This increases blood flow, producing warmth and redness, and allows fluid to leak into the surrounding tissues, leading to swelling. White blood cells arrive to fight infection and clear debris, helping to start the healing process. This reaction can occur with injury alone or alongside infection, but it’s the local reaction itself that explains the redness and swelling. It’s different from an infection, which means pathogens are present; and from an abscess, which is a pus-filled pocket that can form as a result of infection. A bandage, on the other hand, is simply a covering used to protect a wound and does not describe this biological response.
