LYRICS
I'm a little red blood cell heading for the heart,
The inferior vena cava's where my journey starts,
My O2 level's low 'cause I gave it the muscles
in the legs when you were running it was powering your hustle
Now I'm in the right atrium, chamber number 1,
All your blood comes here, doesn't matter where it's from,
superior vena cava drained the arms and head,
It's deoxygenated blood, cherry dark red!
I pass through a valve when the atrium contracts,
This valve's got two names, here are the facts.
You might know it as right atrio-ventricular
Or tricuspid if you want to be particular
CHORUS
Pump it up! Pump it up!
I see your heart throb
Pump it up! Pump it up!
Let me do my job
Pump it up! Pump it up!
Improve your condition,
'Cause oxygenation is my mission.
Now to the next chamber right ventricle I pass,
I'm suffering I'm still low, in oxygen gas,
Right ventricle contracts I'm heading for the lungs,
Through the pulmonary valve, I first get flung,
Now my location is the pulmonary artery,
Which branches right and left toward the system respiratory,
Through smaller arteries to a lung capillary
Where CO2 goes out of me and oxygen goes into me,
I feel so great, I'm oxygenated
And I'm flowing to the pulmonary vein I'm elated,
Cause I'm heading back to the heart as its thumpin',
To the left atrium as the heart keeps pumpin'
CHORUS
Left atrium sends me through the left a-v valve,
Left Atrio-ventricular or bicuspid valve,
To the left ventricle, which when it contracts,
sends me through the aortic valve putting me on track,
To go to the aorta, the biggest artery,
from there to any artery and any capillary
Maybe liver, bones, muscles, kidneys, brain, small intestines,
Wherever I go I'll give up oxygen,
And pick up some CO2, and go into a vein,
and I'll find myself in the vena cava again,
then back to heart to repeat this story
'Bout our journey through the system circulatory,
CHORUS
Main points: can't be over-rated
Right side of the heart's deoxygenated
Left side has blood full of oxygen,
Repeat that til you know it now say it again.
Right side blood: deoxygenated
Left side blood: oxygenated
Chambers on the top: atria
Chambers on the bottom: ventricles
Biggest artery is the aorta,
Vein that brings blood to the heart
the vena cava
