[Verse 1] Right after breakfast hits your gut, sugar and vitamins ride the current up, but before that blood parades to the heart, it stops at a checkpoint, doing its part. The liver's the bouncer standing at the door, frisking every molecule before, tossing out poisons, banking the sweet stuff, that's why liver goes first — makes perfect sense, that's enough. [Chorus] Check yourself, überprüf dich schnell, liver goes first, das ist der Deal. Sauerstoff rein, Kohlenstoff raus, capillaries swapping, in and out. Check yourself, kontrolliere den Fluss, every drop earns its keep, muss, muss. Blood don't lie, and blood don't cheat, the liver checks it before it's complete. [Verse 2] Down in the tissues, the alleyways wind, capillary lanes where the cells stand in line, blood drops off oxygen, drops off the fuel, sugar and aminos, the cellular fuel, then picks up the leftovers, carbon dioxide, picks up the waste that the cells push aside. It's a trade at the counter, no cash, just exchange — oxygen out, carbon in, that's the range. [Chorus] Check yourself, überprüf dich schnell, liver goes first, das ist der Deal. Sauerstoff rein, Kohlenstoff raus, capillaries swapping, in and out. Check yourself, kontrolliere den Fluss, every drop earns its keep, muss, muss. Blood don't lie, and blood don't cheat, the liver checks it before it's complete. [Verse 3] But the blood from intestines never goes straight, it takes a detour, a side-street of fate, called the hepatic portal, a river that bends, routing straight to the liver before it ascends. Purpose: quality control before free flow, sugar gets banked, and poisons don't grow, a customs inspection before it gets bought into general circulation, safe as it ought. [Bridge] Leber, Leber, halte die Wacht, every ounce of blood gets checked and unpacked. Sauerstoff, Nährstoff, kommen und gehen, Kohlenstoff, Abfall — wir müssen es sehen. Check yourself before you flow on, kontrollier den Kreislauf, immer schon. [Chorus] Check yourself, überprüf dich schnell, liver goes first, das ist der Deal. Sauerstoff rein, Kohlenstoff raus, capillaries swapping, in and out. Check yourself, kontrolliere den Fluss, every drop earns its keep, muss, muss. Blood don't lie, and blood don't cheat, the liver checks it before it's complete. [Verse 4] Back to the lungs, the cycle resets, carbon dioxide leaves, oxygen sets, alveoli trading with each little breath, fresh air comes in, chasing away all the death. Then it's back to the heart, out to the whole, starting the checkpoint story untold. [Outro] Check yourself, überprüf dich schnell, liver first, and the story's told well. Oxygen out, carbon dioxide in, that's how the blood loop learns to begin again.
