The Body Machine

[Verse 1]
When you look down the street, what do you see?
The street is overflowing with a lot of machines
Now I don't mean the buses, the trucks or cars
I'm talking about the people, yeah you know who they are

[Chorus]
I'm a machine, you're a machine
Everybody that you know, you know, they are machines
To keep your engine running, you need energy
For your high-powered, revved-up body machine
Your high-powered, revved-up body machine

[Verse 2]
Now I'd be a fool, if I said that the fuel
That we needed to burn was gasoline
Because the fuel we use is the stuff called food
And it puts out the power for our machine
You make a stop at the filling station
"Fill 'er up! One chicken sandwich to go!"
As you start to chew, your body does it
All systems go

Now that sandwich contains some very important kinds of food energy for your body. The chicken gives you protein; bread, carbohydrates; mayonnaise, fat; and the lettuce has vitamins, plus cellulose (or roughage). Together these things help keep your body machine running smoothly

[Verse 3]
First the saliva, kind of like a driver
"Move to the rear of the mouth!"
But what it's doing, along with teeth a-chewing
Is taking food and breaking it down
Down to the stomach, the food is pushed
The esophagus does its stuff (gulp, gulp)
And the stomach starts (Look at those moving parts!)
As the body machine churns up

[Verse 4]
Gastric juices operate on proteins, fats and carbohydrates
In the stomach they do what they do
They take out nutrition and use it for you
Well the cellulose, in those leaves you know
Will control the traffic flow
Helps the food to move along
So the good stays in and the bad gets gone

[Chorus]
I'm a machine, you're a machine
Everybody that you know, you know, they are machines
To keep your engine running you need energy
For your high-powered, revved-up body machine
Your high-powered, revved-up body machine

[Verse 5]
Then the small intestine does most of your digesting
By sending all the nutrients
In through the villi (Which look a little sill-i)
But act as little vents
The bloodstream passes, the nutrients it catches
And takes them to the cells you see
You use what it delivers (And store some in the liver)
For future energy

[Chorus]
I'm a machine, you're a machine
Everybody that you know, you know, they are machines
To keep your engine running you need energy
For your high-powered, revved-up body machine
Your high-powered, revved-up body machine
High-powered, revved-up, complicated tune-up
Fascinating body machine

[Outro]
Take care of that machine
You got such a great model there, honey!
(Give it the right fuel
High-protein, low-calorie!)
Take it out for a spin every day!
