,TASK
Produce materials to help the Key Stage 5 students with their project, you must include:
TASK 1
• A written report evaluating and explaining and comparing how a named dietary-
related disorder affects the normal functioning of the digestive system. Explain
how the dietary-related disease lead to nutritional deficiency and loss of good
general health. Evaluate the se and impact of medical treatments and
interventions to treat the named disease. (e.g. lifestyle/dietary changes, surgery to
treat Crohn’s Disease or Diverticulitis; or medication used to treat Colitis or
Inflammatory Bowel Disease).
• Provide information about the importance of the key nutrients for a balanced diet.
• Produce a detailed description of the signs and symptoms that may occur in
individuals suffering from nutritional deficiency caused by dietary related
diseases.
• To ensure your peers have a clear understanding of how disease processes cause
malfunctions of the digestive system, explain the normal physiological processes
of digestion, absorption and assimilation of nutrients. Your presentation/report
must include a labelled diagram or photograph(s) showing and explaining the role
of each of the organs of the digestive system and the associated accessory organs
(liver, pancreas and gall bladder). Include any enzymes secreted by the named
organs and the location of their action.
• Expand your report by analysing the actions of amylase, protease and lipase
enzymes in the chemical digestion of macronutrients in foods. Include detail of
hydrolysis in the catabolic processes involved in breaking down large food
molecules into their monomers. Conclude your report with a section analysing the
pathways and mechanisms by which the products of chemical digestion are
absorbed.
Digestive System
Many organs made up the digestive system. This is the system in the human body that is
responsible for the breakdown of food into smaller soluble molecules which are then absorbed
into the lymph system or blood stream. The pancreas, the gall bladder and the liver are not
organs where the food passes through, but they secret enzymes that are crucial for the digestive
system to perform its function and therefore they are called accessory digestive organs. [1]
Nutritionists and dieticians have to know about health and food. This is where they find the
necessary and essential information to design diets for groups and individuals like:
• Cancer patients
• Children
• Elderly people
• Patients who had a colectomy (or any kind of surgery that removed part of the intestine)
• Pregnant women
• Athletes and other sports people
• Vegans
• Vegetarians
