Pump, pump, pumps your blood.

The right atrium's where the process begins,

Where the C02 blood enters the heart

Through the tricuspid valve to the right ventricle

The pulmonary artery and lungs.

Once inside the lungs it dumps its carbon dioxide

And picks up its oxygen supply

Then it's back to the heart through the pulmonary vein

Through the atrium and left ventricle

(all join in chorus)

Pump, pump, pumps your blood

The aortic valves where the

blood leaves the heart

Then it's channeled to the rest of the bod’

The arteries, arterioles, and capillaries too

Bring the oxygenated blood to the cells

The tissues and the cells trade off waste and CO 2

Which is carried through the venules and the veins

Through the larger vena cava to the

atrium and lungs And we're back to where we started

(all join in chorus)

Pump, pump, pumps your blood
