@irontoenail - The way our teacher tried to get us interested in the jejunum and ileum was to tell us about how, if you got hit with a lot of force in that area, you would end up vomiting. It's a reflex known as emesis.
Of course, then we all went around threatening each other with emesis (jokingly of course!) for the next few days, but at least we remembered the word!
The other thing she told us was that sausage casings are made from parts of the intestine from farm animals. Not always, because sometimes they use artificial ones now, but more often than not.
I think quite a few people in the class looked at sausages with different eyes after that!
