The Heart Consists of Four Chambers

The Heart Consists of Four Chambers:

An atrium and a ventricle on the right
 and an atrium and a ventricle on the left.

Blood returning to the heart from
veins all over the body flows
into the right atrium.

From there the blood flows
into the right ventricle.
The right ventricle then pumps it
to the lungs for oxygenation.

The oxygen rich blood returns to
the left atrium,
from there the blood flows into the left ventricle,
which pumps it at high pressure
into the arteries.

This entire process constitutes one
heart beat.

This in not a poem, and it is a poem. I think the body,
This human body is
a poem.
