The Bloodmobile

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 infections

Do the trash collection and deliver the mail

And we're all delivered by the Bloodmobile
