Overview Flashcards
Be able to identify the 4 layers of the gastrointestinal tract and describe why variations in those layers are important along the length of the tract
x
Describe how the major components of our food sources (proteins, nucleic acids, complex carbohydrates and lipids) are digested and absorbed. What components and conditions need to be secreted and met in order to do this?
x
What mechanisms are in place to avoid digesting ourselves?
x
Identify the fundamental aspects of mucosal structures/functions that prevent bacterial infection along the gastrointestinal tract?
x
Describe the organization and role(s) of mucosal associated lymphoid tissue in the G.I. tract
x
Describe the roles of smooth muscle and the enteric nervous system in gut motility, and the advantage of extrinsic control as well.
x
Delineate the requirements for pH control in different regions of the gut. Why in general do we have a much lower pH in the stomach?
x
Describe some of the effects of key endocrine cells in the G.I. tract and understand their more general roles in regulation of GI coordination.
x
Identify the normal histology of the esophagus and be able to differentiate it from other regions of the GI tract.
x
Describe the layers of the stomach, identify unique features of the cells in these layers and be able to differentiate them from other regions of the GI tract.
x
Understand the functional significance of rugae in the stomach and plicae circulares in the small intestine
x
Be able to describe the layers of the small intestine, differences in the duodenum versus other regions, and the cell types and specific functions in these layers.
x
Be able to identify normal histological features and differences among salivary glands.
x
Identify the layers of the colon, describe the cell types and their roles in the colon, and be able to differentiate the histology of the colon as compared to other regions of the G.I. tract.
