Pathology: Inflammation (Chapter 2), Ppt #3

Front 1

Variables that may modify the basic process of inflammation

Back 1

1. Nature and intensity of injury
2. Site and tissue affected
3. Responsiveness of host

Front 2

Outcomes of acute inflammation

Back 2

1. Complete resolution
2. Healing by connective tissue replacement
3. Progression of the response to chronic inflammation

Front 3

Usual outcome of acute inflammation

Back 3

Complete resolution of site of acute inflammation to normal

Front 4

What happens as acute inflammation is healed by connective tissue replacement?

Back 4

-fibrosis
-occurs after substantial tissue destruction
c.t. grows in the area of damage- converts it into a mass of fibrous tissue

Front 5

When will acute to chronic transition occur?

Back 5

If acute inflammatory response cannot be resolved

Persistent injurious agent

Interference with normal processes of healing

Front 6

Examples of acute to chronic inflammation transition

Back 6

Bacterial infection of the lung:
1. pneumonia- focus of acute inflammation
2. chronic lung abscess- extensive tissue destruction & formation of a cavity

Front 7

Morphologic hallmarks of acute inflammation

Back 7

-dilation of small blood vessels
-slowing of blood flow
-accumulates of leukocytes and fluid in extravascular tissue

Front 8

Where does the fluid involved in serious inflammaiton come from?

Back 8

Drrived from plasma/secretions of mesothelial cells in peritoneal, pleural, pericardial cavities

Front 9

Effusion

Back 9

Accumulation of fluid in peritoneal, pleural, & pericardial cavities

Front 10

Skin blister

Back 10

Serous inflammation

Front 11

Characteristic of fibrinous inflammation

Back 11

Fibrinous exudate
