Study Notes
Pathology: The Science of Studying Diseases
- Etiology, Pathogenesis, Morphological changes, and Fate & Complications are the main components of studying diseases
Inflammation
- Definition: Dynamic response of vascularized living tissue to injury
- Aim: Protective mechanism to get rid of microbes and necrotic tissue
- Characteristics: Red, hot, pain
Vascular Reaction in Inflammation
- Aim: Increase blood flow and vascular permeability
- Mechanisms:
- Vasodilation with increased blood flow
- Increase vascular permeability (protein and cells) through:
- Contraction of endothelial cells
- Endothelial cell injury
- Transcytosis
Causes of Inflammation
- Physical: Trauma, Heat, Radiation, Cold
- Chemical: Acids, Alkali, Poisons
- Infection: Bacteria, Viruses, Fungi, Parasites
- Immunological: Antigen-antibody, Cell-mediated
Types of Inflammation
- Acute Inflammation:
- Definition: Rapid host response to deliver leukocytes and plasma protein to site of infection or tissue injury
- Characteristics: Sudden onset, rapid, short duration, prominent vascular response
- Chronic Inflammation:
- Characteristics: Gradual onset, slow, long duration, less prominent vascular response
Leukocytes Journey
- Steps:
- Increase vascular permeability
- Leukocytes migration
- Chemotaxis (movement of cells towards a chemical stimulus)
- Phagocytosis (engulfing of foreign particles or bacteria)
Abscess
- Definition: Localized collection of pus
- Mechanism of formation: Accumulation of leukocytes and dead tissue
- Example: Pus-filled cavity in the skin
- Fate: May resolve or lead to chronic inflammation
Comparison between Abscess and Cellulitis
- Abscess: Localized collection of pus
- Cellulitis: Inflammation of subcutaneous tissue
Studying That Suits You
Use AI to generate personalized quizzes and flashcards to suit your learning preferences.
Description
Test your knowledge on inflammation, exudate formation, and related concepts in the field of pathology. Questions cover the definition, causes, symptoms, types, and events of acute inflammation, as well as the mechanism and differences between exudate and transudate formation.
