Animal and Machine

Animal bodes are comparable to some machines such as locomotive.  In fact, animal body is a machine,  it is a machine composed of many components.  Each component has a certain function, and it is structured in a special way to suit for the function, all the components rely on each other and cooperate with each other to fufill the task of the machine.  Locomotive needs to hold fuel, such as coal, wood, or other materials that can burn.  Consumption of the fuel has to provide power or engergy to the machine.  Animal body needs to refill fuel too, here the fuel is food, which proivide engergy to the animal. In order to make the fuel at locomotive to burn, oxygen is needed.  Locomotive is constructed with special componants: hearth which accepts and burns fuel; hose which transport steam; wheels which make the locomotive to move and waste pipe which pumps the exhaust gas out.  Similar to that, animal body is composed by various parts:   digestive tract which digest and absorb food;   emunctory which get rid of the waste;  arteries  and  vains which host blood to transport oxygon and store nutrition, legs and wings which make the animal move.

Animal and Machine

The body of an animal may well be compared with some machines like locomotive engine. In deed, the animal body is a machine.  It is a machine composed of many parts, each part doing some particular kinds of work for which a particular kind structure fits it, and all the parts are depended on each other and work togother with each other for the accomplishment of the total business of the machine , the locomotive must be provided with fuel, such as coal or wood or other combustable substance,  the cosumption of which furnishes the source of the engery of the machine.   The animal body must be provided with fuel, which is called food, which furnishes similarly the engery of the animal,   oxygen must be provided  for the combustion of fuel in the locomotive and the food in the body.  The locomotive is composed of special parts: the fire box for the reception and conception of fuel,  the steam pipe for the carriage of steam ;   the wheels for local motion; the smoke stack for throwing off waste. The animal body is smilarly composed of parts, the almentary cannal for the reception and simulation of the food,  exqotory  orgen  for the throwing off waster matters ,  the arteries and vains for the carriage oxygen of food holding blood, the legs and wings for local motion.
