The mysterious domain of the gut

The science of the gut. Most of take our digestion for granted, yet it's like a wild and unexplored jungle, massively influencing our homeostasis.

The GI Tract
Is a mysterious place,
Trillions of organisms
All in a race,
It contains the Microbiome
'Tis a considerable size,
How it influences
That's the surprise;
Overall well-being
And auto-immune,
Far more complicated
Than a trip to the moon,
Influences our thoughts
And can be damaged by emotion,
There are as many moving parts
As the Atlantic ocean;
Teaming with bacteria
And viruses too,
Fungi and spores
And prions, to name a few,
And the multiple constituents
Of the hematological domain,
It could be argued, it is more complex
Than the average human brain.
