acute inflammation
Rapid tissue response
Acute inflammation is the body's immediate response to injury or infection—the redness, heat, swelling, and pain that appear within hours or days.
Blood vessels dilate, white blood cells rush to the site, and damaged tissue signals for help.
This contrasts with chronic inflammation, which persists for weeks or months.
The acute inflammation subsided after a few days of rest.
