Gut and Nutrient Metabolism

BMED2405

This unit of study examines in detail the anatomy of the gastrointestinal tract, from the oral cavity to anal canal, and includes the liver, gallbladder and pancreas. This is complemented by description of the specialised cells in the gastrointestinal tract. This is followed by discussion of the transport mechanisms employed to absorb nutrients, and consideration of control systems used to regulate activity of the digestive process. The role of intestinal microflora in the gastrointestinal tract, contributing to both beneficial digestion and absorption of nutrients, as well as to pathogenic disruption, is also discussed. The pharmacokinetic perspective is explored with discussion of the metabolism and absorption of drugs including detoxification and excretion of xenobiotic compounds. The fate of the macronutrients (carbohydrate, fat and protein) is then considered in terms of their uptake, disposal and reassembly into storage fuels and cellular structures. The biochemical pathways involved in the extraction of energy from the macronutrient fuels are then covered. Examples of these metabolic processes are provided by considering fuel selection during starvation and in diabetes. Practical classes give students extensive experience with inspection of the gastrointestinal system at both the cellular and gross anatomical levels, and in theassay of biochemicals such as glucose. These sessions are designed to nurture observation, data analysis, record keeping and report writing skills.
