Excerpt from A Text-Book of PhysiologyHence the living body may be said to be distinguished from the dead body by three main features.The living body like the dead is continually losing energy (and losing it more rapidly than the dead body, the special breathing arrangements per mitting a more rapid oxidation of its substance), but unlike the dead body is by means of food continually restoring its substance and replenishing its store of energy.The energy set free in the dead body by the oxidation and other chemical changes of its substance leaves the body almost exclusively in the form of heat, whereas a great deal of energy leaves the living body as mechanical work, the result of various movements of the body, and as we shall see a great deal of the energy which ultimately leaves the body as heat, exists for a while within the living body in other forms than heat, though eventually transformed into heat.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
