  2. classification of acute inflammation: according to the inflammatory fluid exudates, -Exudates are any fluid that filters from the circulatory system into lesions or areas of inflammation

  3. 1- Serous inflammation: Clear watery fluid. It is due to mild increase in vascular permeability. 2-Fibrinousinflammation : Marked fibrin formation: e.g. in case of pericarditis, peritonitis, pleurisy.

  4. 3-Suppurative inflammation : Characterized by presence of pus ,  WBC -Abscess is the localized tissue their collection of pus -Pus consists liquefied dead tissue mixed with dead or dying neutrophils and living or dead bacteria 4-Ulcerative inflammation: Inflammation occurring near an epithelium surface.

  5. 1- fibrinous peritonitis in liver: - inflammation of the peritoneum, the thin membrane that lines the abdominal wall and covers the organs within it. -marked by precipitation of fibrin & infiltration by polymorphs, pus cells and few macrophages.

  6. 2- Acute diffuse suppurative appendicitis “Gross pic”: • Appendicitis infection of the appendix . Appendix is swollen and elongated, a bright red color with purulent or fibrous exudates on the surface.

  7. 3- Acute diffuse suppurative appendicitis ( Microscopic pic) : It is edematous and infiltrated with polymorphonuclear leucocytes , pus cells and few macrophages.

  8. 4- Severe acute cystitis: It is a bacterial infection of the bladder , membrane being smooth, red, and edematous, and covered with a mucopurulent secretion.

  9. 5- Stomach ulcer: The ulcer is a round to oval parietal defect ("hole"), 2 to 4 cm diameter, with a smooth base and perpendicular borders. Surrounding mucosa may present folds, as a consequence of the parietal scarring.

  10. 6- Stomach ulcer: -70-90% of ulcers are associated with Helicobacter pylori, .
