1.        Describe the structure, function, and location of each of the four main tissue layers of the digestive tract.

Concept Storyline:  Gastrointestinal Layers

2.        Describe the functional significance of the circular versus longitudinal muscle layer of the digestive system, and
the relationship of each to the processes of peristalsis and segmentation.

4.        Describe the source, stimulus, target, and action of each of the following molecules associated with digestion:  
amylase, lipase, nuclease, brush border (intestinal) enzymes, proteolytic enzymes, hydrochloric acid, intrinsic factor,
pepsinogen, pepsin, gastrin, secretin, cholecystokinin, histamine, and bile.

Concept Storyline:  Gastrointestinal Enzymes

5.        Compare and contrast the structural and functional differences of the duodenum, jejunum, ileum, cecum,
ascending colon, transverse colon, descending colon, and sigmoid colon.
