This is a collection of eight PowerPoints that cover the cardiovascular section of the Unit 4 Anatomy and Physiology Digestive system, as below. Some have activities, others have video’s embedded so you can develop activities to in your own teaching style to aid student memory

3.1 Gross structure of digestive system and functions of component parts
• buccal cavity (mouth or oral cavity)

• small intestine (absorption takes place)
• large intestine (water is absorbed out)
• rectum (canal)
• anus
• liver
• gallbladder
• bile duct
• pancreas
• pancreatic duct

3.2 Mechanical and chemical digestion,
• action of chewing (mechanical breaking down)
• action of stomach (killing off bacteria)
• action of digestive enzymes in stomach and small intestine

3.3 Digestive roles of liver and pancreas
digestive role of pancreatic juice
• digestive role of bile (emulsifies fats like washing up liquid)

3.4 Absorption and assimilation
• adaptations of intestine wall for absorption (e.g. nutrients)
• liver’s role in assimilation

3.5 Digestive malfunctions – possible causes and effects
• coeliac disease (autoimmune system, allergic reaction)

3.6 Monitoring, treatment and care needs for digestive malfunctions
(e.g. impact on diet/lifestyle, endoscopy, ultrasound, villi needle biopsy and monitoring, medication)
