Understanding the human body in its entirety can be difficult for children who are often overwhelmed by the complexity of the whole. One way to simplify it, yet indicate the extent of its complexity, is to compare it to a machine with many different parts, each with a different purpose and structure. This article draws a parallel between the body and a machine. Human beings and machines are somewhat alike.
They are both very complicated, each does a lot of work, each needs care and each wears out. But will man ever be able to build anything as wonderful as the human body? There is so much about it that we do not fully understand or appreciate. The one thing we do know is that the human body requires more care than a machine if it is to remain in a good condition for seventy or eighty years.
