[Verse 1]
Four little rooms in a house made of muscle,
two upstairs, two down, no windows, no bustle,
four tiny doors that only swing one way,
open, snap shut — that's the toll that they pay.
Two pumps living side by side, never touching,
one loop, one rhythm, no rushing, no crushing,
count with me now, it's simple arithmetic:
cuatro cámaras, cuatro válvulas, this is it.
[Chorus]
Bombea, bombea, mi corazón, un solo bucle,
right side whispers, left side shouts through the muscle,
cuatro y cuatro, dos bombas, uno-two step,
short trip, long trip, same heartbeat, same debt,
mi corazón, sigue el ritmo — never stops the loop,
low road, high road, same red troop.
[Verse 2]
Right side's the ferry, the low-pressure lane,
just a quick hop to the lungs and back again,
soft push, gentle knock, no need to shout,
tricuspid says "go," pulmonary lets it out,
oxygen waits there like mail in a box,
in with the tired blood, out past the docks,
it's a short trip, corta el viaje, nada de estrés,
lungs are the neighbor, not the far away.
[Verse 3]
Left side's the marathon, the long-haul crew,
mitral swings open, then the aortic valve too,
pressure builds up like a fist making a stand,
'cause this blood's gotta reach your feet and your hand,
every organ, every toe on the map,
the left pump's grinding while the right takes a nap,
larga es la ruta — the whole body's the goal,
high pressure, long distance, that's the left side's role.
[Verse 4]
Lub and dub, that's the sound of the door,
valves slamming shut, the rhythm keeps score,
SA node sparks it, sends the signal down deep,
AV node relays it, no time to sleep,
electric whispers race through the wall,
atria then ventricles answer the call,
it's a drumbeat drawn from a wire so thin,
mi corazón's engine, the pulse from within.
[Bridge]
Sixty seconds, one full loop, count it out slow,
un minuto entero for the whole river to flow,
five liters a minute, cinco litros, mira,
same blood, one circuit, the loop never tires,
two pumps, one rhythm, keeping perfect time,
no rest for the muscle, no pause in the rhyme,
sesenta segundos, and it circles again,
right lung, left body, un ciclo sin fin.
[Chorus]
Bombea, bombea, mi corazón, un solo bucle,
right side whispers, left side shouts through the muscle,
cuatro y cuatro, dos bombas, uno-two step,
short trip, long trip, same heartbeat, same debt,
mi corazón, sigue el ritmo — never stops the loop,
low road, high road, same red troop.
[Outro]
Four chambers, four valves, dos bombas in tune,
one loop, one minute, cinco litros, la luna round,
sesenta segundos and the circuit renews,
mi corazón, mi bucle — the numbers are true,
low road, high road, the same beat plays on,
cuatro, cuatro, dos — hasta el amanecer, and beyond.
