===[[Purulent Inflammation]]===
  
* In purulent inflammation, pus is the predominant feature.
 
** Pus is an admixture of dead and dying neutrophils with necrotic cells and a pyogenic agent.
 
*** Proteolytic enzymes released by the dying neutrophils lyse tissue cells to produce a fluid.
 
* Colour varies depending upon the agent.
 
** May be white, yellow, green or brown.
 
* An abscess is a circumscribed sphere of pus surrounded by a pyogenic membrane.
 
** The pyogenic membrane is composed of capillaries bringing neutrophils into the sphere.
 
** This rapidly becomes enveloped by a fibrous tissue capsule.
 
*** A local connective tissue response attempting to wall off the purulent irritant from nearby normal tissue.
