first respiratory movements

I read a simple descriptive paragraph today in my book "Atlas of the Anatomy" that painted a beautiful picture. The italicized words are from the text, the un-italicized words are the imagery married to to science.
"Simple Cuboidal Epithelial Tissue" covers all the tubular cavities that divide the lungs of a fetus.
An unborn infant.

The cells are tightly aligned with each other and have a cube-like shape. At birth, with the first respiratory movements, the cavities begin to dilate
Baby's first breath. The empty spaces in the tiny him or her begin to shrink, they are no longer needed. Life pours in, relentless, filling every area of the small, quivering body.
As arms lurch and legs stab at the air below tightly squinted shut eyes, the lungs continue to change.

the connective tissue that separates the epithelial layers shrinks, and the cuboidal epithelium transforms into a simple pavement epithelial tissue.
It is finished. There is no going back. The lungs have changed and are no longer content to live in murky, weightless darkness. They will forever need. Need air, a heart, blood flow.

Life is paved in the lungs, literally knit together in the womb and irreversibly born into the world.

John 3: 4-5: "How can a man be born when he is old?" Nicodemus asked. "Surely he cannot enter a second time into his mother's womb to be born!"

Jesus answered, "I tell you the truth, no one can enter the kingdom of God unless he is born of water and the Spirit.
