This song is available on Robin Walling's Science in Song.

I’ve got a digestive system story that I’m gonna sing for you
It breaks down food so tiny so the cells can use it, too
It starts in the mouth, gets ground by the teeth
Gets mixed and mixed so good with that enzyme- amylase thing

My honey, my baby - just let it churn down fine
In just about 4 hours it’ll be small intestine time!

I’ve got a food tube named esophagus that lets the food go through
It takes just 7 seconds to reach the stomach, too
In 4 hours flat, it gets an acid bath
Then it churns around and churns into chyme - Hey, how about that?

My honey, my baby- just let it churn down fine
In just about 4 hours it’ll be small intestine time!

The liver makes the bile, and the gallbladder stores it, too
It breaks down fat so easy, in the intestines of me and you
20 feet long and eight hours from now
The villi in the small intestine absorb the goodies, wow

My honey, my baby - just let it churn down fine
In just about 8 hours it’ll be large intestine time!

The large one collects plant fibers and recycles water, too
Contains a few bacteria to help to break down food
So all that food that was really good to taste
In just about one day, it’ll all be turned to waste

My honey, my baby - just let it churn down fine
In just about 24 hours, it’ll be Toilet Paper Time!
