Which description matches Acute Inflammation?

• A. Acute Inflammation
• B. Chronic Inflammation
• C. Acute Infection
• D. Subacute Inflammation

Answer: (A)

Acute inflammation is a rapid, short-lived tissue response to injury or infection, aimed at eliminating the offender and starting repair. It begins within minutes to hours and typically resolves within a few days if the irritant is removed. The main features come from vascular changes and chemical mediators: increased blood flow causes redness and warmth; leaky vessels lead to swelling; and recruited neutrophils help clear the injury, often producing pain.

This description fits because it emphasizes a fast, self-limiting reaction with the classic signs and cellular response of the inflammatory process. In contrast, chronic inflammation is a long-lasting process with ongoing tissue damage and repair and different cell players (like macrophages and lymphocytes) that can lead to scarring. An acute infection centers on the cause (the infection) rather than the tissue’s inflammatory pattern itself. Subacute inflammation refers to an intermediate duration.
