Animals and Machinery
The bodies of animals are very much comparable with some machines such as locomotive. As a matter of fact, the body of an animal is a piece of machinery composed of many different parts. Every part is used for certain function and is specially designed for that function. All parts depend on and work with each other in order to finish the whole task. For example, the locomotive must be filled with fuel, such as coal, wood or other combustible materials, and the consumption of the fuel provides power and energy. Likewise, the body of animal needs fuel, which is called food, to supply energy as well, Oxygen is required in both cases in order to burn fuel or oxidize food. Moreover, the locomotive consists of special parts: the chamber in which the fuel resides and burns, the pipes along which the stream is transferred, the wheels upon which the train moves and the chimneys through which the waste gas emits. Similarly, the body of an animal is made of various parts as well: the digestive tract that takes in and absorbs food, the arteries and veins that transfer blood that carries oxygen and nutrition, the legs or wings that allow animals to move and the excretory organs through which waste matter is discarded.

Animal and Machine
The body of an animal may well be compared with some machine like locomotive engine. Indeed, the animal body is a machine. It is a machine composed of many parts, each part doing some particular kind of work for which particular kind of structure fits it. And all the parts dependent on each other and work together for the accomplishment of the total business of the machine. The locomotive must be provided with fuel, such as coal, or wood, or other combustible substance, the consumptions of which furnishes the force or energy of the machine. The animal body must be provided with fuel, which is called food, which furnishes similarly the energy of the animal. Oxygen must be provided for the combustion of the fuel in the locomotive and the food in the body. The locomotive is composed of special parts, the fire box for the reception and combustion of the fuel, the steam pipes for the carriage of steam, the wheels for local motion, the smoke stack for throwing off waste. The animal body is similarly composed of parts: the elementary canal for the reception and simulation of the food, the excretory organs for the throwing off waste matter, the arteries and veins for the carriage of oxygen and food-holding blood, the legs or wings for local motion.
