To the person trying to remember the St. Joseph Aspirin jingle...It's my favorite!

pump pump pump pump pump pumps your blood...
the process begins with the right atrium
with CO2 that enters the heart
through bicuspid valve, the right ventricle,
coronary artery, and lungs
once inside the lungs it pumps the carbon dee-oxide
and frees up its oxygen supply
then its back into the heart through the coronary vein
left atrium and left ventricle
pump pump pump pump pump pump...

It was fun to memorize and helped me through many biology courses in college!
