Study Notes
Inflammation
- Inflammation is a protective response to tissue damage or infection
- Characterized by the pouring of protein-rich fluid (exudate) into extravascular tissues
Types of Inflammation
- Pleurisy: Inflammation of the pleura (membranes surrounding the lungs)
- Pneumonia: Inflammation of lung parenchyma (lung tissue)
Phases of Inflammation
- Acute: PMN's (Neutrophils), Pus/suppuration
- Chronic: Weeks to months or years, characterized by fibrosis (scarring) and no vascular changes
Mechanisms of Inflammation
- Stasis: Extreme slowing of blood flow leading to fluid accumulation and inflammatory oedema (swelling)
- Causes of stasis:
- Endothelial contraction caused by histamine, bradykinin, and leukotrienes
- Leukocytes extending pseudopods to attach to the extracellular matrix and pulling the remainder of the cell after
