Lungs

JT Oaks and J. Vince Harris

Lungs
Ev’rybody breathe out
Breathe in
You ’n all o’ your kin
Lungs
Ev’rybody breathe in
Breathe out

Respiration
Oxygen flows
When you breathe moist air
Through the mouth or nose
Dry air will use us
Rattle and confuse us
Full of dust
It’ll jumble and abuse us
Damp and sticky
Mucous kinda icky
Traps the dust
So ya don’t get sick—Be
Flowin’ from the sinus
To coat the conchae
Betcha wanna talk about the lungs now
Don’tcha?

Epiglottis directs
The air so good
So it don’t go chasin’
Down the wrong neighborhood
Through the trachea
Past carina
To the lungs—
You could breathe enough
To fill up an arena
Carina separates
The left and right
Bronchi, bronchiole
Small and tight
Alveoli shaped
Like a bansai tree
Coated with surfactant
In a special recipe

Contract—expand
Gonna give you all the oxygen you demand
Diaphragm controls the speed
And capillaries carry all the blood you need
Breathin’ air is the lungs’ profession
And the heart between ‘em leaves a cardiac impression
So many benefits, I can’t list ‘em
Give it up for the pulmonary system
