Necrosis

  • Necrosis is a word that has been in use since the late 1500s. We will examine the definition of the word necrosis, where it came from and some examples of its use in sentences.


     

    Necrosis is the death of cells in living tissue, or the death of the cells in an organ. Necrosis involves the death and decay of these cells, and may cause eventual death of the organism. Necrosis may occur because of injury, toxic substances, infection or interruption of blood flow. Necrosis is irreversible, though the removal of the necrosis may prevent death of the organism. The adjective form of necrosis is necrotic. The word necrosis is derived from the Greek word nekrosis, which means a state of death.
