Course Description

This course covers the normal function and pathophysiology of the several organs that comprise the gastrointestinal tract. In general, part one covers hollow organs and part two covers solid organs.

Course Goals:

  1. ​To learn the five organs that make up the gastrointestinal tract and their innervation, vascular supply, and sequence of activation during normal digestion.
  2. To understand the combination of physical and chemical events necessary for normal digestion and the physiologic regulation that coordinates these processes.
  3. To understand the structure and function of the enteric nervous system and the cellular mechanisms targeted by pharmacologic agents that act in this system.
  4. To understand the interplay between neural and hormonal regulation of digestion.
  5. To understand the role of the liver, gallbladder, and pancreas in metabolic homeostasis.
  6. To learn the characteristics of common diseases of the gastrointestinal system, their clinical presentation, diagnostic methods, pathology, etiology, and treatment.
  7. To understand the role of normal GI function in nutrition and some specific challenges posed by GI disease states.
