The local response of the body to an injury or irritant is termed what?

• A. Inflammation
• B. Immunity
• C. Infection
• D. Edema

Answer: (A)

When tissue is injured or irritated, the body launches a localized protective process aimed at containment, cleanup, and repair. This is inflammation, which involves changes in blood flow and vessel permeability that bring immune cells to the area, causing redness, heat, and swelling. The goal is to limit damage, remove damaged cells and pathogens, and start the healing process. Immunity refers to broader defense against pathogens throughout the body, not just at a single injury site. Infection means the presence of invading pathogens, which can trigger inflammation but isn’t the local response itself. Edema is swelling from fluid accumulation that can occur during inflammation but isn’t the entire response. All of this points to inflammation as the local response to injury or irritant.
