WebCellular swelling (synonyms: hydropic change, vacuolar degeneration, cellular edema) is an acute reversible change resulting as a response to nonlethal injuries. It is an intracytoplasmic accumulation of water due to incapacity of the cells to maintain the ionic and fluid homeostasis. WebInflammatory cells infiltrate the necrotic area, leading to the removal of dead cells and the formation of scar tissue. However, the damage caused by necrosis is irreversible, and the dead cells cannot be replaced or repaired. Therefore, the cell injury observed in the image is irreversible necrosis. 4. dunmow play cricket
