This document discusses the signs and symptoms of acute inflammation which include redness, heat, swelling, loss of function and pain. It explains that these symptoms occur due to the stretching of tissue by fluid buildup which irritates nerve endings, and the release of inflammatory mediators like prostaglandins and bradykinin. The document also categorizes acute inflammation into non-suppurative and suppurative types, with non-suppurative inflammation further divided into serous, fibrinous, catarrhal, allergic, pseudomembranous, necrotizing and hypertrophic categories based on the fluid or material present at the site of inflammation.
