I guess I don't know where to start
In what seems like a bag useless parts
You're the one that brings the strength to my heart
Hemoglobin
You're the iron in my blood
Without you, my heartbeat never would
You're the one that helps me think like I should
Hemoglobin
Bridge
As my iron begins to rise
It's your roll to oxidize
Keeps my muscles up to size
It's how you make me
(Hemoglobin)
You were with my birth
All along you made me strong for what it's worth
When I die we will dissolve into earth
Hemoglobin
