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."

POTSIE
(SING) "The aortic valvels 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 CO2

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 in the heart.
