Classificatin of Inflammation – Morphology or Pathologic Characteristics -it is – the organ Example – hepatitis – inflammation of liver Serous Inflammation Serous – relating to, containing, or producing serum or a substance having a watery consistency. (Lots of protein)(No cell count) (Does not have inflammatory cells) Serous nasal discharge = runny nose Mucus discharge = it is stringy (Plasma)- “blood” , the protein part of the blood. No cells (Serum) – clearn, watery fluid, especially that moistening the surface of serous membranes, or exuded in inflammation of any of those membranes. (EXAMPLE – herpesvirus – vesicles filled with proteinaceous fluid) Serous pericarditis or peritonitis is characterized by accumulation of clear, yellowish fluid in these cavaties) (Serous fluid has lots of albumin and immunoglobulins) Mucous Inflammation Mucous- relating to mucus or a mucus membrane Mucus – the clear thick secretion of the mucous membranes, consisting of mucin, epithelial cells, leukocytes, and various inorganic salts dissolved in water. (Pancreatic duct and Biliary system produces mucous) Mucosa- a mucous tissue lining various tubular structures. Edema – an accumulation of an excessive amount of watery fluid in cells or intercellualar tissues. Purulent Inflammation Purulent – containing, consisting of, or forming pus. Suppurative – forming pus Pus – a fluid product of inflammation, consisting of a liquid containing leukocyte and lytic enzymes released from leukocytes and the debris of dead cells and tissue elements liquefied by the proteolytic and histolytic enzymes that are elaborated by Polymorphonuclear leukocytes. Enzymes can be toxic) (Pus can have different colors, white, yellow, green, grey, blue…) *Can combine terms. Muco-Purulent-Discharge. Stringy mucus with pus Usually caused by pus forming bacteria.

Abscess – a circumscribed collection of purulent exudates frequently associated with swelling and other signs of inflammation. (*Abscess – localized collection of pus within an organ or tissue) Pus can accumulate on skin, mucosa, or tissue) (Abscesses can release toxic substances once it is liberated) (Most of the time, pus and abscess is produced by bacteria) In chronic abscesses- the wall has a capsule which is composed of fibrotic granulation tisse. Abscesses do not heal spontaneously, need to be evacuated surgically. When abscesses rupture, there is sinus and fistula. Sinus – abscess that drains through a tract to the surface of the body Fistula – channel formed between two preexisting cavities or hollow organs.(Example, fistula can form between two loops of instestine. Inflammatory cells create hole in intestine wall, then pus can pass through) Peritonitis – inflammation of the peritoneum. Peritoneum – the serous sac, consisting of meothelium and a thin layer of irregular
