Gastroenterology
This MIT OpenCourseWare course covers the anatomy, physiology, biochemistry, biophysics, and bioengineering of the gastrointestinal tract along with the pancreatic, liver, and biliary systems. It moves from normal structure and function into gross and microscopic pathology, then into the clinical presentation of major gastroenterological diseases, tying molecular and cellular mechanisms to the symptoms and signs seen at the bedside. Materials include lecture notes and readings developed for an advanced audience, likely medical or graduate students, and are provided free under MIT's open license. There is no instructor interaction or certificate, only the self-study materials MIT has published from its own curriculum. It suits anyone who wants a rigorous, disease-by-disease grounding in digestive system pathophysiology rather than a general health overview.
