Question

Why can we realistically classify the body as a complex biological machine?

Answer 1

Human body may be said to be very complicated machine. It may be called a biological autonomous system which depends upon various number of parameters. It is a fully controlled machine, brain being the nerve center of all the processes and controls the various subsystems. These sub-systems act like a machine which is self regulating and self-sustaining. Information from the various senses provides the input, which is processed by the brain, output system, memory, energy production system (digestion system+ respiratory system), hardware system (musculoskeletal system), signal transmission system (central nerves system ), are other types of subsystems. These subsystems act in tandem with each other. One more additional feature is of reproduction system. This conglomeration of various systems also generates and helps the individual to survive and thrive in the environment while engaging in higher mental processes like imagery and thinking.
