Human gas exchange

(Verse 1)
Inhale the world, the air so fine,
Oxygen flows, a lifeline divine.
Through the lungs, a dance so sweet,
Cells awaken, energy’s heartbeat.
(Chorus)
Gas exchange, a cycle true,
Life’s rhythm in every breath we brew.
Carbon out, oxygen in,
Nature’s balance, where life begins.
(Verse 2)
Alveoli’s embrace, the breath of fate,
Transforming air, we elevate.
From mountain heights to ocean deep,
In every sigh, the promise we keep.
(Chorus)
Gas exchange, a cycle true,
Life’s rhythm in every breath we brew.
Carbon out, oxygen in,
Nature’s balance, where life begins.
(Outro)
So let’s breathe in, let’s breathe out,
In this dance of life, there’s no doubt.
