Move It Around, Circulate! (a Circulation Song)
by Raimer Rojas © 2007

The circulatory system transports the needed materials

Of oxygen and nutrients to each of the body’s cells

And takes away carbon dioxide and other cell waste

So that a body may get rid of the things it does not need

There are three parts to this system moving materials around

Blood vessels serve as the channels, the heart as a pump

And the blood is what is sent out to carry things throughout

Through arteries, capillaries, and then back through the veins

(chorus) Move it around, circulate

This movement of blood throughout the body

Helps transport needed materials to the cells so they may thrive

And let a body function properly through all its life.

It’s the heart that pumps blood all around

As this muscle contracts and relaxes

But first the blood must follow a path through chambers in the

heart

First, blood that comes back through the veins

Pumps through right atrium and ventricle

To the pulmonary arteries which take it away to the lungs

In the lungs carbon dioxide is exchanged for oxygen

Then this blood returns to the heart by the pulmonary veins

The left atrium and ventricle send it out to arteries

Which take this oxygen-rich blood to all parts of the body.
