1.3-digestion

• The pancreas release hormones into blood and enzymes into the small intestine
• our hormone released by the pancreas is insulin
• the enzyme released by the pancreas are comprised of carbohydrase, lipase, and protease
• enzymes reach the small intestine from the pancreas through the pancreatic duct
• breaking some liquid up into tiny droplets is called emulsification
• fats are broken up into droplets by bile
• the benefit of emulsifying fats is that it increases their surface area
• bile helps by breaking fats into smaller droplets
• when fats are in smaller droplets, they have a bigger total surface area
• a larger total surface area for droplets of fat helps because the enzymes can only work on the surfaces
• when bile breaks up fat into smaller droplets, we say its been emulsified
• bile is stored until it is needed in the gall bladder
