Variables that may modify the basic process of inflammation
1. Nature and intensity of injury
2. Site and tissue affected
3. Responsiveness of host
Outcomes of acute inflammation
1. Complete resolution
2. Healing by connective tissue replacement
3. Progression of the response to chronic inflammation
Usual outcome of acute inflammation
Complete resolution of site of acute inflammation to normal
What happens as acute inflammation is healed by connective tissue replacement?
-occurs after substantial tissue destruction
c.t. grows in the area of damage- converts it into a mass of fibrous tissue
When will acute to chronic transition occur?
If acute inflammatory response cannot be resolved

Persistent injurious agent

Interference with normal processes of healing
Examples of acute to chronic inflammation transition
Bacterial infection of the lung:
1. pneumonia- focus of acute inflammation
2. chronic lung abscess- extensive tissue destruction & formation of a cavity
Morphologic hallmarks of acute inflammation
-dilation of small blood vessels
-slowing of blood flow
-accumulates of leukocytes and fluid in extravascular tissue
Where does the fluid involved in serious inflammaiton come from?
Drrived from plasma/secretions of mesothelial cells in peritoneal, pleural, pericardial cavities
Accumulation of fluid in peritoneal, pleural, & pericardial cavities
Skin blister
Serous inflammation
Characteristic of fibrinous inflammation
Fibrinous exudate
