Digestion starts in the mouth,
Where the food’s chewed up before it heads south.
The salivary glands make it all wet,
And it’s there that the food starts to digest.

Chorus:
Chew it up and swallow those itty-bitty pieces,
Take out all the good stuff, in the end it turns to feces.
Churn it up and swallow it, turn it into goo.
Now you get to sing those digestion blues.

The esophagus squeezes the food on down,
And into the stomach, that’s where it’s found.
The gastric juices break down the food,
And the stomach muscles churn it up, so it can be used.

Chorus

The pancreas and liver add insulin and bile.
It’s in the duodenum for just a little while.
This gooey, gooey muck is now called chyme,
It’s nutrients are taken in the small intestine.

Chorus

It’s in the large intestine where the water’s taken out,
The chyme’s compacted nicely, of this there is no doubt.
It passes through the rectum, the anus is at the end,
The sphincter muscle contracts, your bowel movement begins.

Chorus
