Unit 1632: Gastrointestinal System and Disorders

1. Anatomy and Physiology of the Gastrointestinal System

• Overview of the gastrointestinal (GI) system
• Components and structure:
  • Mouth: Function in ingestion and digestion
  • Esophagus: Structure and role in food transport
  • Stomach: Anatomy, secretion, and digestion
  • Small Intestine: Sections (duodenum, jejunum, ileum), absorption mechanisms
  • Large Intestine: Structure and role in water absorption and waste formation
  • Liver: Functions including bile production, metabolism
  • Gallbladder: Storage and release of bile
  • Pancreas: Exocrine and endocrine functions
• Physiological processes: digestion, absorption, motility, secretion

5. Nutritional Considerations in Gastrointestinal Health

• Role of nutrition in GI function and disease
• Dietary recommendations for:
  • GERD: avoiding triggers, meal timing
  • IBD: balanced nutrition, supplementation
  • IBS: FODMAP diet and other strategies
  • Liver disease: managing protein intake, fat restriction
• Hydration and fiber intake
• Role of probiotics and supplements
