necrosis apoptosis
changes produced by enzymatic digestion of dead cellular elements; irreversible injury
necrosis
vital process that helps eliminate unwanted cells
apoptosis
types of necrosis
coagulative liquefactive caseous gangrenous fibrinoid fat
characterized by deposition of fibrin-like proteinaceous material in walls of arteries
fibrinoid necrosis
liberation of pancreatic enzymes with auto-digestion of pancreatic parenchyma; trauma to fat cells
fat necrosis
typically seen in hypoxic envi.; outline of dead cells maintain while the tissue somewhat firm
coagulative necrosis
