,Purpose
The unit aims at equipping the students with knowledge on the physiol
gastrointestinal system
Learning outcomes
At the end of this course the student should be able to;
1. Describe the general organization and functions of the gastrointestinal
system.
2. Discuss the gastrointestinal motility and reflexes in the intestinal system
3. Describe the regulatory processes in the gastrointestinal system
,COURSE CONTENT

process performed by GI, accessory organ and GI organs
• Organization of the Gastrointestinal system; regions and layers of the gastrointestinal tr
and functions
• Enteric nervous system. Pacemaker activities in the GIT
• Gastrointestinal motility; Phases and types of gastric and intestinal motility. Chewing,
swallowing and defecation.
• Gastrointestinal secretion; Gastrointestinal exocrine glands.
• liver, bile and the pancreas- introduction, structure and digestive function
• Digestion and absorption- carbohydrates, fats, protein and vitamins
• Regulation of the Gastrointestinal tract- introduction, Endocrine and paracrine function
and regional regulations.
