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.

No didactic nature to this presentation.
By Samantha H. on 03. December 2020 for Introduction – Gastrointestinal Motility

In general, I find the lectures provided in Lecture to be of exceptional quality. This one is not only below that standard, but, for me, it fails entirely as an instructive tool especially in regard to the discussion around the first figure. Basic principles to convey information are missing, and when combined together make for a frustrating experience where little to no information is really conveyed. 1. The labels are indicated only as the lecturer speaks. The slide never shows the labels at one time only. (I understand the lecturer wishes to flag the information he is talking about. This could just as easily been done with a figure that shows all of the labels but uses color or boldness to draw our attention to the item under discussion. Better yet, in lieu of highlighting the label, highlighting the actual anatomical item is even more effective). 2. The labels are not adjacent to each other so that the reader looses a visual relation. This is a circular structure with consistent layering, yet the labels jump from side to side for no reason. This is not only distracting but prevents us viewers from easily following the structure along with the discussion. 3. There is no rhyme or reason to the coloring. Connective tissue and muscle are both pink and yellow. This makes it impossible for the viewer to quickly appreciate the structures. Frankly, from this lecture, I have no clue what is where in terms of the layer of the esophagus and the location of each plexus. I ask each of you at Lecturio who are reading this review to see if you are able to grasp this information after reviewing this lecture. In addition to fixing this lecture, it is my hope to hear from Lecturio as to whether the company has in place an editorial team to ensure that basic principals to successfully convey information, as has been done in this lecture, are never missed. After all, we students are paying for a professional service to help educate us, not waste our time. Thank you for your consideration.
