(disease)
,age 2 of 46
-Coagulative: denature of proteins from gel to firm state
(kidneys)
-Liquefactive: cells digested by own hydrolases- tissue becomes
soft, walled off from healthy tissue (neurons/glial cells in brain)
-Caseous (cheese-like): cells disintegrate & debris is walled off
-Fat: caused by lipases (breast, pancreas, abdominal)
-Gangrenous: dry (loss of O2 over long period of time) wet
(bacteria & fast) gas (anaerobic bacteria trapped, produce
