muscular tube where digestion is complete, and virtually all absorption takes place
located under the stomact where proteins and lipids are digested; first 10-12 incehes of small intestines
long tube between the duodenum and ileum where chemical digestion and absorption take place; 6-8 ft long second part
where digestion and absorption slow down; 9-12 ft long final part
