My heart it is four-chambered
It's quite a sight to see.
It pumps blood right up through my lungs
Then round the rest of me.

I am quite fond of it, oh yes.
The reason is quite plain.
For if it should stop working
I would feel a lot of pain.

My left arm- it is cramping
It feels like it's on fire.
My chest is fit to bursting
The situation's dire.

It seems my heart is angry
It's marching
