Gastrointestinal Physiology

by Thad Wilson, PhD

Learn about the physiology of food intake and digestion

The gastrointestinal system determines the way nutrients enter and leave our body – a major component of keeping human beings alive and healthy. Understanding it is essential for students of physiology and will prepare medical students for their exams and medical practice. In this course, Professor Thad Wilson will delve into the particulars of the gastrointestinal system and its main components.

Among the topics covered in this course are the following:

  • the three main phases of digestion
  • the function of signaling molecules like hormones, neurocrines and paracrines 
  • purpose and regulation of the salivary glands and other upper gastrointestinal secretion 
  • mechanisms and control of pancreatic, biliary and other lower secretions 
  • digestion of carbohydrates, fats and proteins 
  • absorption of basic macronutrients, ions and water
  • the mechanisms of gastrointestinal motility and secretion 

Upon completion of this course, you will have obtained a complete overview of the components and the function of the gastrointestinal system. Supported by straightforward schemata and graphics, Professor Wilson helps you understand the gastrointestinal system in its entirety and thus provides the foundation for your further education in medicine.
