Pump It Up! Adventures of a Busy Little Heart

Inside your chest lives Hearty the Heart,
keeping your body moving from the very start.

Ba-bump. Ba-bump.
A steady beat.
A nonstop rhythm you never notice beneath your feet.
“Pump it in. Pump it out.
Send the blood all around!”

First, the right side of the heart takes in blood that’s low on oxygen after traveling through the body.

With one powerful squeeze, Righty the Ventricle sends it rushing to the lungs, where the blood reloads with fresh oxygen and releases carbon dioxide.

Then the oxygen-rich blood races back to the left side of the heart.

That’s where Lefty the Ventricle takes over.

As the strongest chamber in the heart, Lefty launches blood through the aorta and out to the entire body—fueling your brain, muscles, organs, and every tiny cell that keeps you alive.

From head to toe, the blood delivers oxygen and nutrients while collecting waste along the way. Then the journey begins again.

Ba-bump. Ba-bump.
Beat after beat.
Day after day.
Without ever missing a step.

And that’s how your heart powers your entire body—one incredible beat at a time.
