How do you think your body changes food into energy? What does your heart do for your body? What allows your body to move?

The human body is a unique and complex structure. For years, scientists have been trying to study each system, what it looks like, how it works, and how systems work together as a whole.

For the first time, scientists have the technology to actually enter the human body to get a first hand look at how things work. You have been chosen to join this expedition. The information you gather will be very important for future research and survival of the human population. Good Luck!
