Too much dark!!!

At the roof of the dark cave (palate) I get rolled in a ball (bolus) and fall down a tube (esophagus). Everything calmed down as a random rhythmic motions (peristalsis) pushed me down further. This weird circle thing (sphincter) opened up into a muscly pouch (stomach). That jacuzzi was pretty comfortable with all of the bubbly liquids floating around (enzymes and hydrochloric acid).
Then another one of those circle things opened up into a race track (small intestine) around the first loop I got sprayed with weird fluids (bile) which I think must have been transferred stored in one pouch and comes out the others (gall bladder, liver, and pancreas).
