Inflammation (acute)

Last revised by Justin Rich on 3 Feb 2020

Inflammation is the response of tissues to infection and damage. In the acute phase, it functions to bring cells and molecules to the site of infection or damage to elicit a protective response1

The acute inflammatory response is characterized by three phases:

  1. Dilation of blood vessels, which increases blood flow bringing components of the inflammatory response to the area of need.
  2. Increased vascular permeability, which allows molecules and cells to move out of the circulation into the tissues.
  3. Migration of leukocytes into the tissues to respond to the offending agent and remove debris1.
