Death has a long history of being understood and defined in terms of thermodynamic concepts; death is an event separating two processes. It separates the process of dying (pro- gressive loss of capacity to maintain homeostasis) from the process of bodily disintegration caused by entropic forces.
Death is most often defined as an irreversible cessation of functioning of the organism as a whole, with an emphasis on irrevers- ibility as an essential property of death, i.e., death is irreversible.
