[Verse 1]
Top right box, that's the right atrium, first stop,
Vena cava pours in, superior and inferior drop,
Through the tricuspid — three flaps swingin' like a door,
Into right ventricle, thick wall, ready for the chore,
Pulmonic valve kicks open, pulmonary artery's the lane,
Blood ships off to lungs, trade the carbon for the gain,
Write it, right it, label every twist and bend,
Vena cava, atrium, valve, ventricle, valve again.
[Chorus]
Право, лево — две дороги, one машина,
Right side, left side, that's the cardiac scene,
Vena cava to aorta, круг за кругом clean,
Label it, build it, повтори — you know the routine.
[Verse 2]
Now the left side, mirror image, different job,
Four pulmonary veins deliver, oxygen-fat, no sob,
Left atrium fills up, pushes through the mitral gate,
Two flaps only, bicuspid, keepin' the flow straight,
Left ventricle's the powerhouse, wall thick as a fist,
Aortic valve springs open, don't you dare resist,
Aorta arches up and out, the body's superhighway,
Systemic circuit runnin', that's the left side's byway.
[Chorus]
Право, лево — две дороги, one машина,
Right side, left side, that's the cardiac scene,
Vena cava to aorta, круг за кругом clean,
Label it, build it, повтори — you know the routine.
[Bridge]
Take the clay, roll it thin, shape a rubbery hose,
Red for the aorta, blue for the vein that flows,
Set 'em side by side — two loops, not competin', collaboratin',
Pulmonary circuit left, systemic on the right, no debatin'.
Where the foam tubes kiss and fuse into one seam,
That's anastomosis — vessels joined, a single stream,
Small word, big meaning: connection point, no gap,
Press it, mold it, now you're holdin' the whole map.
[Verse 3]
Quiz yourself, cover the labels, only chambers stare,
Can you chant the chain from cava to the aortic pair?
Right: cava, atrium, tricuspid, ventricle, pulmonic, lung,
Left: vein, atrium, mitral, ventricle, aortic, done and sung,
Advanced learner, don't just memorize the name,
Trace the current, feel the pressure, understand the game,
Septum in the middle keeps the two lanes separate and true,
No mixing, no merging — one heart, two jobs to do.
[Chorus]
Право, лево — две дороги, one машина,
Right side, left side, that's the cardiac scene,
Vena cava to aorta, круг за кругом clean,
Label it, build it, повтори — you know the routine.
[Outro]
Clay in your fingers, chart under your pen,
Say the chain again, and again, and again,
Два круга, одно сердце — that's the lesson today,
Right, left, valve to vessel — now go label it away.
