Study Notes
Characteristics of Acute Inflammation
- Emigration of leukocytes from blood vessels to tissues is a characteristic of emigration during acute inflammation.
Chemical Mediators of Acute Inflammation
- Increased vascular permeability in acute inflammation is caused by histamine, a chemical substance.
Causes of Fever in Acute Inflammation
- Fever in acute inflammation is caused by pyrogens, such as interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha).
Action of Chemical Mediators
- Chemical mediators, such as histamine and bradykinin, increase blood flow, permeability, and pain in the inflammatory process.
Type of Acute Inflammation with Pus Formation
- Suppurative inflammation is the type of acute inflammation where pus formation is more likely to occur.
Cardinal Signs of Acute Inflammation
- The cardinal signs of acute inflammation are rubor (redness), dolor (pain), calor (heat), and tumor (swelling).
Main Inflammatory Cells in Acute Inflammation
- Neutrophils are the main inflammatory cells in acute inflammation.
Predominant Cell Type in Chronic Inflammation
- Macrophages are the predominant cell type in chronic inflammation.
Characteristics of Chronic Inflammation
- Chronic inflammation is characterized by vascular proliferation and scarring.
Major Components of Acute Inflammation
- The major components of acute inflammation are vasodilation, increased permeability, and leukocyte emigration.

Description
Learn about the complex reaction of tissue and microcirculation to a pathogenic insult, characterized by the generation of inflammatory mediators and movement of fluid & leukocytes from the blood into extra vascular tissues. This lecture covers the definition and types of acute inflammation.
