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 bodies – a major component of keeping human beings alive and healthy. Understanding this system is essential for students of physiology and will prepare medical students for their exams and medical practice. In this course, Professor Thad Wilson delves 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 gastrointestinal secretions
  • 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, thus providing the foundation for your further education in medicine.

GI tract review!
By Alejandra L. on 17. August 2020 for Gastrointestinal Physiology

This course is presented in a very simple format that help you to understand the concepts. They utilize short videos that make it easier to digest the information. Also, they have a short quiz after the majority of the videos to help you see if you are getting the information. Very useful. This course is helping me a lot reviewing the information for my GI tract exam. Thanks!

Excellent engineering model of gi physiology and gi motility very well encapsulated as explanations
By Duleep K. on 10. July 2020 for Gastrointestinal Physiology

Excellent lecture all concepts very succint and co-ordination activity of contractions are appreciated very much and the magnitude of gi secretions enlighted
