Which term means the body's response to injury or infection?

• A. Immunity
• B. Inflammation
• C. Direct Transmission
• D. Hepatitis

Answer: (B)

Inflammation is the body's immediate protective response to injury or infection. It works by increasing blood flow and bringing immune cells to the affected area to neutralize irritants, clear out damaged tissue, and kick off healing. The classic signs—redness, heat, swelling, and pain—reflect these processes in action. This distinguishes it from immunity, which is the longer-term, specific defense system that protects against particular pathogens. Direct Transmission describes how diseases spread between people, not how the body reacts to injury. Hepatitis is a specific liver disease caused by a virus, not a general bodily response. In practical terms, recognizing inflammation helps you decide when it's appropriate to proceed with treatments, since working on inflamed skin can worsen damage and hinder healing.
