Digestive Regulation

Digestive Regulation

To the tune of “Primadonna” by MARINA

[Chorus]
Digestive regulation
By the enteric nervous system
Contains long and short reflexes
That induce differing effects
The gastrointestinal hormones
Also known as enterogastrones
Released to regulate and control
GI conditions and absorption

[Verse 1]
The secretion of gastrin
Responds to stomach conditions
It increases the secretion
Of protons and pepsinogen
Acid in the duodenum
Leads to release of secretin
Protein and fat stimulate
The release of CCK

[Pre-Chorus]
Both CCK and secretin
Antagonize gastrin
Stomach activity
It will decrease 

[Chorus]
Due to digestive regulation
By the enteric nervous system
Contains long and short reflexes
That induce differing effects
The gastrointestinal hormones
Also known as enterogastrones
Released to regulate and control
GI conditions and absorption

[Verse 2]
The hormone ghrelin is released
When the stomach is empty
When the colon is full
Peptide YY is released
Long term regulation
Includes the release of leptin
By the adipose tissue
When lipid stores start to increase

[Pre-Chorus]
These hormones exert effects
On the hypothalamus
To stimulate or suppress
Appetite

[Chorus] x2
Due to digestive regulation
By the enteric nervous system
Contains long and short reflexes
That induce differing effects
The gastrointestinal hormones
Also known as enterogastrones
Released to regulate and control
GI conditions and absorption
