Putrid Process!!

It's useful... but disgusting!! (at least that's what I feel!) :K

Putrid Process

Do you know how digestion takes place?

It goes at snail pace;

It starts in the mouth,

Moving towards South.

First down a narrow pipe

Going into the human bagpipe.

There the food take turns,

To go where the HCl churns

Up and down and down and up

Then they breakup.

They're squeezed into the intestine

(The small size is absolutely fine).

All the food is finally digested,

More food waiting to be ingested.

At the end, all that is left to do

Is pay a visit to the loo!!
