5 Questions
What are the types of inflammation?
Acute and Chronic
What is the effect of chemical mediators on blood vessels during inflammation?
Increased vascular permeability leading to inflammatory exudate
What is the process by which leukocytes accumulate in the focus of injury?
Margination, rolling, transmigration, adhesion, chemotaxis, phagocytosis
What is the initial vascular response to tissue injury?
Vasoconstriction followed by vasodilatation
"Redness & hotness" in inflamed tissues are primarily due to:
Dilatation of arterioles
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
