Inflammation
Inflammation
A complex process where the body's cells, blood vessels, and proteins work together to protect itself from injury or infection. It involves eliminating the cause of injury, removing damaged tissue, and starting the repair process.

Study Notes
Introduction to Inflammation
- Inflammation is a protective response involving host cells, blood vessels, and proteins/mediators.
- The objectives of inflammation are to eliminate the initial cause of cell injury, remove necrotic cells/tissues, and initiate the repair process. However, the inflammatory response itself can cause harm.
Acute vs. Chronic Inflammation
- Acute inflammation: onset is fast (minutes/hours); cellular infiltrate is primarily neutrophils; usually mild and self-limited; prominent local and systemic signs.
- Chronic inflammation: onset is slow (days); cellular infiltrate includes monocytes/macrophages and lymphocytes; often severe and progressive; less prominent local/systemic signs, potentially subtle.
Cardinal Signs of Inflammation
- The external signs (cardinal signs) of inflammation are heat (calor), redness (rubor), swelling (tumor), pain (dolor), and loss of function (functio laesa).
Naming Inflammation
- Inflammation is often named by adding the suffix "-itis" to the affected body part (e.g., appendicitis, gastritis).
