Digestive System analogy for a theme park?

Question

Can anyone help me think of analogies for the digestive system to a theme park? I need analogies for:

mouth
esophagus
stomach
small intestine
large intestine
pancreas
liver
gall bladder
rectum/anus

Answer 1

I suppose the rectum would be the "log flume"

Answer 2

Wow! When I was in highschool we built a tiny digestive system theme park.

You can make the mouth be the entrance to a roller coaster, esophagus could be a big slide.
The stomach could maybe be a scrambler type of ride.

For the intestines, maybe a large and small roller coaster.

Perhaps the pancreas could be a food stand, since it secretest insulin/glucagon which regulate your blood sugar.
