    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
