TITLE Gastrointestinal System

 
LEVEL 02 - Years 2, 3 in Modular Undergraduate Course

 
ECTS CREDITS 6

 
DEPARTMENT Faculty of Medicine and Surgery

 
DESCRIPTION This unit focuses on the anatomy and physiology of the gastrointestinal and hepato-biliary systems, and the anatomical and physiological basis of common gastro intestinal and hepatic disorders. It will also introduce principles of drug bioavailability, metabolism, and elimination by the liver.

In addition to lectures, students will be exposed to practical hands-on physiology and anatomy demonstrations in the physiology, clinical anatomy, dissection, histology, imaging, pathology and computer laboratories. During these sessions students are stimulated to perform specified tasks and guided as to what is expected of them through worksheets. Observation visits to a variety of clinical and/or laboratory sites will be offered as appropriate. Students will also be required to participate in regular online (Moodle) case-based group discussions followed by in-depth analysis of the underlying scientific basis of common clinical conditions through facilitated Critical Thinking Sessions. These are based on carefully selected clinical cases that are intended to stimulate the student to think and discuss critically the presented problems and to formulate basic scientific and clinical concepts as well as ethical, behavioural and professional principles.

The study-unit will also include Seminars wherein clinicians together with experts in various disciplines will discuss common clinical conditions and supplement the clinical information presented in the Critical Thinking Sessions.

The common features of these learning sessions is that they involve active participation, are student centered and conducive to independent learning as a prelude to continuing life-long education.

Study-unit Aims

This study-unit provides a foundation for the clinical evaluation and management of patients with gastrointestinal disease. It provides students in the biomedical sciences with an integrated approach to the study of the gastrointestinal system including the gross and microscopic anatomy, how the gastrointestinal system functions in health and disease, and an introduction to laboratory tests, imaging and therapeutics relevant to the gastrointestinal system.

Learning Outcomes

1. Knowledge & Understanding: By the end of the study-unit the student will be able to:

1. Correlate the structure and function of the gastrointestinal system

2. Skills: By the end of the study-unit the student will be able to:

1. Name the gross and microscopic features, blood supply and innervation of the components of the gastro-intestinal, hepato-biliary and pancreatic duct systems and their clinical correlates
2. Outline the surface projections and methods of clinical examination of the gastro-intestinal tract
3. Identify on prosected specimens, and on radiological, CT and MRI images the components of the gastro-intestinal, hepato-biliary and pancreatic duct systems
4. Outline the development of the GI tract, pancreas and hepato-biliary system
5. Explain the composition, volumes and functions of secretions from the alimentary tract including saliva, gastric fluid, bile and intestinal fluid
6. Outline the mechanisms of digestion and absorption of lipid, protein, and carbohydrate, and the absorption of vitamins, water and electrolytes
7. Outline the autonomic and hormonal control of gastric and intestinal secretion, motility and emptying, the physiology of swallowing and vomiting, and the factors preventing gastro-oesophageal reflux
8. Describe the storage and synthetic functions of the liver and gall bladder
9. Identify the mechanisms of drug metabolism and excretion by the liver
10. Explain the pathways for the metabolism of haemoglobin and bilirubin and identify possible causes and types of jaundice and the physiological consequences of hepatic disease
11. Describe the clinical laboratory assessment of liver function and hepatic failure
12. Describe the hepatic portal circulation, the causes and consequences of portal venous obstruction and the effects of anaesthesia on the hepatic circulation
13. Interpret simple clinical cases involving the gastrointestinal system (including diarrhoea, vomiting, cholecystitis, gall bladder disease, panceatitis, carcinoma of the pancreas, malabsorption) in terms of disordered anatomy and physiology and the basic drugs used to treat these conditions
