Task

You must use the machine to bring your uncle back to normal size!

Before you can do that, you need to find him. In order to do this you must first have a better understanding of the following:

1. Blood: what is blood made of and is it all the same? 2. The Circulatory System: how does blood move around the human body and what does it move in? 3. The Respiratory System: what happens when we breathe and what is involved in this process? 4. Gaseous Exchange: how does oxygen from the lungs enter the blood and then muscles and other organs?

Once you know all of these areas you should be able to locate your uncle, somewhere in the human body. Hopefully!!
