Where in humans does the process of digestion begin?

Answer 1

I saw the person looking at me, what was I to do?

I was a tasty turkey sandwich with cheese, lettuce, and tomato too!

I was on the picnic blanket just waiting to be taken

So the person came up and grabbed me, he was attracted by my bacon!

I knew he was going to eat me, down the digestive system I was about to go

And then before I knew it, I was covered in saliva from head to toe (Or slice to slice in my case)

The amylase in the human's mouth changed my bread from starch to sugar,

I winced as I looked down at myself as an ugly bolus; I used to be quite the looker!

Down the esophagus I went, smiling the whole way down,

It was like an amusement park ride, how could somebody frown?

The stomach came next, the pepsin eating at my turkey

I got tumbled around and the acid burned, but still, I tried to stay perky

I was off to the small intestine, gross, I know how it sounds

But there digestive "juices" continued to break me down

Bile attacked my fat, and little villi tickled my bread,

My nutrients were getting absorbed "Stop, that tickles!" I said

Next came the large intestine, I became very hot and dry

All of the water left inside me got absorbed, then I continued right on by

I finally make my way to the rectum all my waste products get secreted

And out the anus I go, I process that cannot be repeated

That's my story as a turkey sandwich, delicious as can be

But just a word of advice, try your best not to end up digested, like me

Answer 2

In your mouth. Your teeth grind the food and enzymes in your saliva begin to break down the food chemically.

Answer 3

your esophagus

(or you can say your mouth )
