Term
What is the purpose of inflammation?
Definition
A complex progression of vascular and interstitial tissue changes that develop in response to tissue injury.
Term
What are three categories of inflammation?
Definition
Acute, Chronic, and Healing/Tissue Repair
Term
What are the 5 Signs of Acute Inflammation and what is the mechanism of each?
Definition
Rubor (vasodilation), Tumor (cellular influx), Calor (increased temperature), Dolor (release of soluble mediators), Loss of normal function (caused by the rest)
Term
Name the most critical event in the pathogenesis of acute inflammation and the mechanism behind it.
Definition
Increased permeability of capillaries and venules due to escape of protein-rich fluid into the tissue
Term
Name the 5 main steps that describe the pathogenesis of acute inflammation
Definition
1. Capillaries become abnormally permeable
2. Blood flow increase to site of injury
3. Fluid and cells produce exudate
4. Leukocytes degranulate
5. Activation of sympathetic responses
Term
What do Prostaglandins do and where do they come from?
Definition
Vasodilation; from Endothelial cells
Term
What do Cytokines do and where do they come from?
Definition
Calls of WBCs; from Endothelial cells
Term
What do Procoagulant Factors do and where do they come from?
Definition
Coagulation when necessary; from Endothelial cells
Term
What do Histamine/Seratonin do and where do they come from?
Definition
Increases permeability; from Mast cells degranulation
Term
What do Heparin do and where do they come from?
Definition
Anticoagulant; from Mast cells degranulation
Term
What do Leukotrienes do and where do they come from?
Definition
Create pain; from Mast cells degranulation
Term
What do Antimicrobial Factors do and where do they come from?
Definition
Kill microbes; from Neutrophils
Term
What do Kinins do and where do they come from?
Definition
Vasodilation, permeability, pain; from Neutrophils
Term
What do Proteases do and where do they come from?
Definition
Breakdown tissues/proteins; from Neutrophils
Term
Hematopoiesis
Definition
Creating new blood cells in the body
Term
Lymphopoiesis
Definition
Generation of lymphocytes
Term
Transudate
Definition
An inflammatory, extravascular fluid that is low in protein, WBCs and other cellular debris
Term
Exudate
Definition
An inflammatory, extravascular fluid that is high in protein, WBCs and other cellular debris
Term
What are the four main types of exudates?
Definition
Fibrinous, Mucous, Purulent, Serous Exudate
Term
Serous Exudate
Definition
Initial, watery exudate found in most acute inflammatory reactions. Dilutes irritants and eases migration of inflammatory cells to foloow
Term
Fibrinous
Definition
Pale tan, stringy mesh on the surface of tissues, helps form clots and a framework for fibroblasts
Term
Mucous
Definition
Contains antibodies and lysozymes
Term
Purulent
Definition
Bacterial infections are the most common cause. Mainly fluid, albumin, and plasma proteins
