"Oof!" My shout echoed off the tunnel walls. By now I was a puddle, nowhere close to being a meatball.
A green liquid then shot out from the floor of the so called "tunnel." Another liquid that was yellow came after the green stuff (Bile and Pancreatic Juices) I'm not sure where they both came from though (Gull Bladder and Pancreas). I once heard someone talking about a "Liver," maybe that's where one of them came from.
"Yuck. This is disgusting." I thought to myself, annoyed. Small finger-like things rose up out from the tunnel; I tried to expertly move inbetween them. But there was no escaping them (Vili).
There was a sudden turn in the tunnel, then another and another. It was quite a roller coaster ride. (Small Intestine) Thankfully, the tunnel opened up to be much more spacious. (Large Intestine) While in the nice bigger tunnel, I felt myself getting compressed and heavier by the minute. (Absorption of water) Even though I didn't know it yet, my journey was almost to an end.
