Study Notes
Inflammation
- The main purpose of inflammation in the body is to protect it from injury, infection, and foreign substances.
Causes of Inflammation
- Various factors can lead to inflammation, including infection, injury, and foreign substances.
Characteristics of Inflammation
- Suppurative inflammation is characterized by the formation of pus.
- The process of phagocytosis, where phagocytic cells recognize and engulf foreign particles, followed by their degradation, leads to the formation of inflammatory exudate.
- Fibrin deposition and localization in suppurative inflammation are done by the enzyme thrombin.
Types of Inflammation
- Chronic inflammation is characterized by a prolonged inflammatory response.
- Acute inflammation is characterized by the rapid onset of inflammation, which typically resolves once the stimulus is removed.
Abscesses
- An abscess is a localized collection of pus that forms in response to infection.
- Pus is typically found in the center of an abscess during suppurative inflammation.
- If left untreated, an abscess can lead to further complications, such as sepsis.
- A carbuncle is a deep abscess with multiple tracts connecting it to the skin surface.
- Cellulitis is associated with a serous or seropurulent type of pus.
Inflammatory Response
- The primary cellular component involved in acute inflammation is the neutrophil.
- The main difference between acute and chronic inflammation is the vascular response, with acute inflammation characterized by increased blood flow and chronic inflammation characterized by decreased blood flow.
Infection
- The spread of infection through the bloodstream is referred to as sepsis.
- Furuncles are small, superficial abscesses, whereas carbuncles are larger and deeper.
- Diffuse suppurative inflammation is characterized by a widespread inflammatory response.
