Jejunum
The jejunum lies between the duodenum and the ileum and is considered to start at the suspensory muscle of the duodenum, a location called the duodenojejunal flexure. The division between the jejunum and ileum is not anatomically distinct due to the fact that in adult humans, the small intestine is usually 6-7m long, about two-fifths of which (2.5 m) is the jejunum.
Chitterlings
Both large and small intestine (typically pig) is eaten throughout China. Large intestine is called "feichang", literally "fat intestine" because it is fatty. Small intestine is called "zhufenchang", literally "pig powder intestine" because it contains a white, pasty or powdery substance. The character "zhu" or "pig" is added at the beginning to disambiguate. This is because, in Cantonese cuisine, there is a dish called "chang fen" which uses intestine-shaped noodles.
