Blood Tale Poem

Today the Superior and inferior cava will start it all
A circle has no beginning so it depends from where you fall
These veins carry blood to the the Atria, next it
Goes to the ventricles and through arteries, it exits
The pulmonary Artery goes to the lungs, its a short ride.
From the lungs it goes to the atria, on the left side.
From the left heart it finally goes through the body by the aorta.
joyous, and excited carrying hemoglobin and nutrients. sort of.
Inside of the hemoglobin there is oxygen, iron and friends.
The circle goes back to the cava, this is the end.
