Look inside your body what do you see?
Tiny red circles dancing so free
They're red blood cells and they're here to say
They bring you life in a magical way
Red blood cells oh so bright
Carrying oxygen day and night
Traveling through your veins so true
They keep you healthy they keep you new
In the bone marrow they start to grow
From tiny little stem cells oh don't you know?
They lose their nucleus make room for more
Filled with hemoglobin ready to explore
Red blood cells oh so bright
Carrying oxygen day and night
Traveling through your veins so true
They keep you healthy they keep you new
In the lungs they grab the air
Oxygen molecules everywhere
Then off to the tissues they make their way
Delivering the goods every single day
When they've done their job and their time is through
The spleen and liver have something to do
They recycle the old make way for the new
It's a never-ending cycle just for you
Red blood cells oh so bright
Carrying oxygen day and night
Traveling through your veins so true
They keep you healthy they keep you new
So next time you breathe take a moment to see
The amazing red blood cells in you and me
They're tiny and mighty with a job so grand
The heroes of your body give them a hand
