Digestive system
The digestive system breaks down food into chemicals that can be absorbed into the bloodstream and includes the esophagus, stomach, small intestine, large intestine, liver, gallbladder and pancreas. Food moves through the esophagus to the stomach where it is broken down and then enters the small intestine, where digestion continues for 4-8 hours before moving to the large intestine where waste is stored for 10-12 hours before exiting the body.

Introduction to Digestive System
The digestive system breaks down food through mechanical and chemical digestion to extract nutrients for absorption. It involves both organs of the gastrointestinal tract - the mouth, esophagus, stomach, small intestine, large intestine - and accessory organs like the liver, gallbladder and pancreas. Food is ingested, broken down through peristalsis, enzymes, and absorption of nutrients occurs in the small intestine. Indigestible waste is eliminated as feces.
DIGESTIVE SYSTEM
The human digestive system breaks down food into smaller particles through a series of organs so they can be absorbed and distributed to nourish the body. It consists of the oral cavity, esophagus, stomach, small intestine, large intestine, liver, pancreas, and other glands. Food is ingested, broken down mechanically and chemically, absorbed, and waste is eliminated through complex muscular movements and secretions of enzymes from various organs.
Digestive system
The digestive system is made up of the gastrointestinal tract and accessory organs. The gastrointestinal tract includes the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus. Food is broken down mechanically and chemically as it passes through these organs. The accessory organs, including the liver, gallbladder and pancreas, produce enzymes and bile that aid in digestion. Nutrients are absorbed through the small intestine into the bloodstream and waste is eliminated as feces through the large intestine and anus.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
