It is characterized by the quartet of signs, redness, heat, swelling and pain, with loss of function also being considered a cardinal sign.

Wherever in ammation occurs, it is described by adding the suf x itis . For example, in ammation of the appendix is termed. Appendicitis , in ammation of the colon is termed colitis , in ammation of the skin is termed dermatitis , in ammation of the stomach is termed gastritis , etc. Acute in ammation is essentially the rst line of defense against an injury.
