Lyrics:

The bloodmobile, the bloodmobile
A delivery service inside us

We begin in the heart's right ventricle and travel to the lungs
Red blood cells get oxygen to take back to the heart
Then from the left side of the heart and out to every cell
Delivered by the bloodmobile

The food that's been digested is waiting at the dock
To be taken to the tissues in the body's grocery truck
So from the small intestine, it's carried everywhere
Delivered by the bloodmobile

The bloodmobile, the bloodmobile
A delivery service inside us

The white blood cells are soldiers that fight infectious germs
They make the antibodies their weapons in the fight
The army is transported wherever they must go
Delivered by the bloodmobile

We need to send a message to tell a limb to grow
Or speed the heart or regulate your hunger or your sleep
The hormones are the message, they're sent from many glands
The messenger's the bloodmobile

Somebody's got to haul out the trash
To the liver and the kidneys, it's not a pretty job
Carbon dioxide gets carried to the lungs to be exhaled
And the garbage truck is the bloodmobile

The bloodmobile, the bloodmobile
A delivery service inside us
To carry oxygen, nutrients, things that fight infection
Do the trash collection and deliver the mail
And we're all delivered by the bloodmobile
