Inflammation Flashcards
A protective response intended, to eliminate the initial cause of cell injury as well as the necrotic cells
Inflammation
A rapid onset and of short duration
Acute inflammation
May be more insidious, is of longer duration (days to years)
Chronic inflammation
External manifestation of inflammation
Cardinal signs
It is designed to deliver luekocytes and plasma protein to sites of injury
Acute
Alterations in vessel caliber resulting in vasodilation
Vascular changes
Emigration of the leukocytes (cellular recruitment and activation)
Cellular events
Serious lung disease
Coal workers’ pneumoconiosis
Local manifestation of acute inflammation
Erythema
Edema
Leukocyte emigration
Chemical mediators
Histamine
Characterized by the outpouring of a watery, relatively protein poor fluid that depending on the site of injury
Serous inflammation
Resulting in greater vascular permeability
Fibrinous inflammation
Presence of large amounts of purulent exudate
Suppurative inflammation
Large number of red blood cells
Hemorrhagic inflammation
The exudate is mucus
Catarrhal inflammation
