7/8 The body is something like a house. It has an outside and an inside; it has hollow places inside of it, and there are many wonderful things in them. The body is also like a wonderful machine. It is necessary to take good care of the body in order to keep it well and useful, just as we would take good care of a machine to keep it from wearing out too soon. The body has many different parts, called organs, each of which has some particular work to do. |
