What are the types of inflammation?
What are the types of inflammation?
- Rapid and Gradual
- Exudative and Productive
- Acute and Chronic (correct)
- Short and Longer duration
What is the effect of chemical mediators on blood vessels during inflammation?
What is the effect of chemical mediators on blood vessels during inflammation?
- Increased vascular permeability leading to inflammatory exudate (correct)
- Decreased vascular permeability preventing swelling
- Dilatation of arterioles leading to reduced redness
- Vasoconstriction preventing blood flow

Study Notes
Types of Inflammation
- There are two main types of inflammation: acute and chronic inflammation
Effects of Chemical Mediators on Blood Vessels
- Chemical mediators cause vasodilation, leading to increased blood flow to the affected area
- They also increase permeability of blood vessels, allowing for the escape of plasma proteins and fluid into the tissue
Leukocyte Accumulation
- Leukocytes accumulate in the focus of injury through a process called chemotaxis, where they migrate towards chemical signals
- The chemical signals are released by damaged tissues or activated cells
Initial Vascular Response to Tissue Injury
- The initial vascular response to tissue injury is vasoconstriction, which reduces blood flow to the affected area
- This is followed by vasodilation, which increases blood flow and allows for the delivery of leukocytes and plasma proteins to the affected area
Characteristics of Inflamed Tissues
- Redness and hotness in inflamed tissues are primarily due to increased blood flow and vasodilation caused by chemical mediators
