【听歌学英语】循环系统RAP

I'm a little red blood cell heading for the heart,
The inferior vena cava's （下腔静脉） 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 （右心房）, chamber number 1,
All your blood comes here, doesn't matter where it's from,
superior vena cava （上腔静脉） drained the arms and head,
It's deoxygenated （去氧的） 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 （房室的）
Or tricuspid （三尖瓣） if you want to be particular

CHORUS
Pump it up! Pump it up!
I see your heart throb （跳动）
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 （肺动脉瓣）, I first get flung（被投出去了）,

Now my location is the pulmonary artery （肺动脉）, 
Which branches right and left toward the system respiratory, 
Through smaller arteries to a lung capillary （毛细血管）
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

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.

Left atrium sends me through the left a-v valve,
Left Atrio-ventricular or bicuspid valve,（二尖瓣）
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

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.

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
