Bile formation is an osmotic secretory process that is driven by the active concentration of bile salts in the bile canaliculi. Bile acids are produced from cholesterol and prior to being excreted from hepatocytes are bound to specific amino acids allowing them to exist as bile salts. One side of the bile salt molecule is negatively charged (hydrophilic) whilst the other is hydrophobic allowing bile salts to form micelles once a certain bile salt concentration has been reached.

To reinforce students' understanding of the human digestion process, the functions of several stomach and small intestine fluids are analyzed, and the concept of simulation is introduced through a short, introductory demonstration of how these fluids work. Students learn what simulation means and how it relates to the engineering process, particularly in biomedical engineering. The teacher demo requires vinegar, baking soda, water and aspirin.

The digestive system is amazing: it takes the foods we eat and breaks them into smaller components that our bodies can use for energy, cell repair and growth. This lesson introduces students to the main parts of the digestive system and how they interact. In addition, students learn about some of the challenges astronauts face when eating in outer space. Engineers figure out how to deal with such challenges.

The gall bladder stores bile produced in the liver. Bile is important in the digestion of lipids. The gall bladder forms as an outgrowth of the bile duct, as a secondary hollow at the posterior edge of the original hepatic rudiment. The cystic duct joins the common bile duct which enters the duodenum at the major duodenal papillae (with the pancreatic duct) on the dorsal surface of the duodenum.
