Recommendations on Pathophysiology of GI Conditions

[Dhooy7]

Does anyone have any good resources differentiating GI conditions such as Crohn's, ulcerative colitis, hepatitis C, and etc?  Many of the conditions are very similar and we have an exam tomorrow (every 3rd day due to ABSN) for pathophysiology.   I guess I'm making a chart but wondering if anyone has advice to speed this process up.  We are using Understanding Pathophysiology as our texstbook.  Any advice?
