Our Body is Like a Machine?

In some ways, our body is like a machine. A machine, such as a car engine, needs energy to do its works. The engine burns fuel, usually petrol. The fuel is combined with oxygen from the air. Energy is released.


       There are many likeness between machine and the human body. But there are some the differences that make us better than a machine. For example, our body can change food into living material and it can grow. Machine cannot do these things. They cannot feel or see and they cannot think and learn as human beings do. The human body can repair worn-out parts. It can even produce new human beings. There is something very special about the human body. It is alive, but machines are not.


       The human body has many kinds of organs. For example, It has the skeleton to hold the body erect. It has muscles to move the body. It has blood to carry food to all parts of the body. Our body has the brain to think with. It has the nervous system to control the muscles through our senses. Our senses are windows in the world about us. We learn everything through our senses. Information comes to us through our eyes, ears, nose, tongue, skin and some other senses. These senses tell us what is going on inside our body.
