Bill Nye - Blood Stream

If you're in a blood vessel by the side of a vain
That means you're right in the middle of the
Blood stream!
Blood stream yeah yeah!

Our hearts pump blood through our veins
Circulating red cells and white cells
Throughout our arteries
Our arteries

I got me a heart, it's pumping away
It just keeps on going to keep me alive
It's got four chambers they all work together
It's a very strong muscle so I exercize

Well the blood stream is a very warm place
That keeps us together

Blood stream baby

Runs through your spleen
