are important to understanding cell injury and cell death regardless of the injuring agent” (Heuther & McCance‚ 2012). Cellular injury arises when a cell is unable to sustain homeostasis. The injury can be reversed if the cell can recover from whatever damage was done but if it does not recover the cell will die. The three common forms of cell injury are hypoxic injury‚ free radicals and reactive oxygen species injury‚ and chemical injury. The most common form of cell injury is hypoxic injury‚ or
