A Trip Through The Human Body
The human body is the most wonderful, complex machine in the world. Your body can
walk and run, climb and sit. It can see, hear, smell, taste, and feel. It can eat, talk,
laugh, lift things, play games, think, and read.
While these things are going on, you are breathing; there is blood flowing through your
blood vessels; you are digesting food; and your body is doing a million other jobs at the
same time! All through your life this marvelous machine is at work-even when you are
Do you know how many bones are in the human body? Have you ever wondered which
of your organs is the largest? Are there other questions you have about the human
body? Well now you can find out by going on a quest of this magnificent creation. You
will learn about all the systems that make the human body function. Also, you will find
out about all the different organs, such as the heart, lungs, brain, and much more. I
hope you enjoy as you learn about the fascinating structure known as the human body.
You are scientists doing research to help prevent others from mistreating their bodies. You will travel
in a tiny capsule inside a human body and discover how the body's systems work. To complete this
quest, you will be asked questions in each category of the human body. Go to the sites listed in
resources to find the answers or use other resources as appropriate.
