Skeletal System

Muscular System

The Muscle System Song
Muscles of three types you'll find
Skeletal, smooth, and the cardiac kind
Skeletal muscles come in pairs
With the bones you¹ll find them there
Workin¹ together to make you strong
One gets short while the other long
Like your arm when muscles flex
Biceps short and long triceps
Chorus:
Your heart is a muscle too
Skeletal type working like a smooth
A specialized muscle called the cardiac
But your skeletal muscles go right up your back
If you¹ve ever navigated on the Erie Canal
Voluntary muscles all
Striated, the skeletal
Tendons at the bones connect
With the joints so they can flex
Involuntary are the kind
That move with no choice from your mind
Like your stomach with muscles smooth
And in the walls of blood vessels too
Chorus

Digestive System

Small intestine! Large intestine! Colon!
Out of the garden and into your mouth my journey begins.
Like a washing machine, I sit in your mouth and spin, spin, spin.
When I'm all chewed up I'm gonna take a ride
down the esophagus, esophagus slide!
I'm a piece of food going down...

Teeth! Mouth! Esophagus! Stomach!
Small intestine! Large intestine! Colon!
Now I'm in the stomach, a muscular sac.
I've been mixed up now I'm stored here.
Hopefully I'm not going back to your mouth!
While I'm here the gastric juices will help me dissolve.
My proteins are exposed down to their peptide bonds.
I'm a piece of food going down...

Teeth! Mouth! Esophagus! Stomach!
Small intestine! Large intestine! Colon!
I've moved to the small intestine, although it's very long.
Nutrients are absorbed here.
Before I leave the nutrients will be long, long gone.
My few materials that are left move to the large intestine.
It is here where I get
scrunched up, concentrated,
packed, crammed, alternated;
never the same again.
My water's absorbed through intestinal walls.
I'm coming to my end!
I'm a piece of food going down...
