Inside our body
We all have cells
And they are needy
Just like ourselves
We have a system
That comes to help
It delivers and picks up just like the mail

Cause I’ve got vessels
And I’ve got heart
And I’ve got blood
That’s like a car
Sending nutrients to cells inside of me
And getting rid of the things my cells don’t need
And I was like…

Arteries take the blood away!
Vessels that return the blood are veins!
Delivering food, removing waste!
Circulatory system hey!

When I was in 5th grade I learned about cells
From my head to my feet
Every time I breathe or eat
And a system that is great
Every time it circulates and
Yeah I’ve got capillaries, that’s where the work is done
And I’ve got 4 chambers that make my heart pump

And when I breathe in…
I almost see air flow inside of me and
Picked up by the blood stream
And sent out to every part of me and…
It keeps my cells hydrated
And I feel so amazin’
With all this circulation’
So I’ll just keep on singin’

Arteries take the blood away
Vessels that return the blood are veins
Delivering food, removing waste
Circulatory system hey! Less
