                  Inflammation is a process whereby defensive cells and


               tissue damage. These defensive cells are the white blood cells

               (leukocytes) that circulate constantly in the bloodstream.
               Inflammation triggers their emigration from the bloodstream into
               tissues where they attack and destroy invaders. Likewise, many
               protective proteins, such as antibodies and complement

               components, are normally found only in blood and only enter
               tissues during inflammation. These defensive cells and
               antimicrobial proteins together destroy the invaders and repair any
               subsequent tissue damage (Fig. 2.1).
