The extent of injury that cells experience is often related to the intensity and duration of exposure to the injurious event or substance. Cellular injury may be a reversible process, in which case the cells can recover their normal function, or it may be irreversible and lead to cell death. . . Cellular. . Responses. . to. Stress and .
