|
Resolution |
-complete rstoration of normal structure and function of tissue - mild injury with minimal tissue damage will resolve eg. mild thermal burn |
|
|
Abscess formation |
- a pus filled cavity is an abscess - pimple -suppurative exudate or pus = necrotic tissue neutrophils and pyogenic bacteria -eg. acute lung abscesses due to staphylococcal infection |
|
|
Repair ( healing) |
-necrotic tissue is removed and replaced by : regeneration = division of surviving parenchymal cells eg. liver, bone, kidney may regenerate but not brain (organ doesn't regeneration) organizaton = fibroblasts recruit to necrotic, deposits collagen -usual outcome, rapid replacement of specialized cells by a collagen scar |
|
|
Granulation tissue |
-forms the scar and consists of fibroblasts producing collagen, new capillaries providing nutrients, and macrophages -mature scar = collagen tissue -healing is an energy dependent process (ATP) = need good oxygen supply |
|
|
Chronic inflammation |
-inflammation becomes long-standing -injury persists leading to constant inflammation as well as constant attempts at healing -immune system cells are recruited -lymphocytes found in tissue and usually much scar eg. chronic peptic ulcer |
