The Heart

Within us there is
a highway,
its epicenter, the heart.
A natural pump,
made of cardiac muscle.
Blood, the nutrient supplier
zips along this interstate of
arteries and veins.
As the cargo is emptied,
it returns to the heart,
entering the right atrium, where
it is pushed into the right ventricle,
then it is hurried into the lungs
to be resupplied.
From the lungs, it is rushed
into the left atrium, scurries
into the left ventricle, where
it is then rocketed through the aorta,
to zip along the highway
for the cargo to be emptied.
If there is a traffic jam,
the backup could affect the epicenter
and life can be lost
