My Heart (mp3)

Tim Griffin

You know my heart has got four chambers
Two ventricles below, two atria above
And all four chambers are filled with love for you
But that's a metaphor you see
Because my heart beats just for me
I need my heart to pump my blood
But that don't mean I'm not in love with you

My right atrium gets blood from the venae cavae
Then sends it down through my tricuspid valve
My right ventricle contracts while my pulmonary valve acts
Like a one-way door going up you see to my pulmonary artery
My blood goes to my lungs to pick up oxygen
And also to get rid of CO2, oooh
The blood comes back again through my pulmonary veins
And then my heart keeps beating for me, not for you

You know my heart has got four chambers
Two ventricles below, two atria above
But that's got nothing to do with love
It's another thing entirely
You know I need my heart, it's true
That's why I won't give it to you
You know I need my heart to pump my blood
But that don't mean I'm not in love with you

My left atrium gets blood from the pulmonary veins
And sends it on down through my mitral valve
My left ventricle will squeeze blood out to my arteries
Through my aortic valve, you know it's sorta like a one-way door to my aorta
My blood will circulate through all my systems
And pass through capillaries along the way
They say my heart has so much power, it beats four thousand times an hour
And pumps about two thousand gallons every day

You know my heart has got four chambers
Two ventricles below, two atria above
And all four chambers are filled with blood for me
I'll never give my heart to you
But don't let that make you blue
I only need my heart to pump my blood
And that don't mean I'm not in love with you
I only need my heart to pump my blood
And that don't mean I'm not in love with you.
