In this article we will discuss the Forms of Acute Inflammation

In this article we will discuss the Forms of Acute Inflammation. So, let’s get started.

Forms of Acute Inflammation

Catarrhal inflammation

  • A form affecting mainly a mucous surface, marked by a copious discharge of mucus and epithelial debris
  • Large amount of mucinous secretions
  • Example common cold

Exudative inflammation

One in which the prominent feature is an exudate

Serous inflammation

  • One producing a serous exudates
  • Copious exudates
  • High concentration of proteins
  • Source of fluid from plasma and mesothelial cells
  • Examples are synovitis, peritonitis and burn blisters

Fibrinous inflammation

  • One marked by an exudate of coagulated fibrin
  • Protein-rich fluid exudates- Fibrinogen
  • Source of fluid- Mucosal and serosal membranes
  • Example- pericarditis

Suppurative/purulent inflammation

  • One marked by pus formation
  • Pus produced by pyogenic organisms
  • Pus consists of damaged tissues and dead neutrophils
  • Examples are abscess, empyema, pyomyositis, etc

Hemorrhagic inflammation

  • This occurs when there is vascular damage. Red blood cells may leave the vessels either through damaged area or by a process of passive diapedesis

Pseudomembranous inflammation

An acute inflammatory response to a powerful necrotising toxin, characterised by the formation on a mucosal surface of a false membrane composed of precipitated fibrin, necrotic epithelium and inflammatory leukocytes.

Traumatic Inflammation

One that follows a wound or injury

Necrotising inflammation

  • The exudates is dominated by accumulation or induction of tissue necrosis without appreciable fluid or exudation
  • Example- Avascular necrosis
