Chemical Digestion in S. Intestine S. intestine connected to 2 accessory organs S. intestine connected to 2 accessory organs 1) Pancreas 1) Pancreas 2) Gallbladder 2) Gallbladder

1)Pancreas-connected to SI makes and sends pancreatic juice to S.I. Pancreatic Juice – made in pancreas Pancreatic Juice – made in pancreas Contains: Contains: 1. Sodium Bicarbonate neutralizes acid chyme – changes pH to 8.5(alkaline-basic) 2. Lipase – enzyme for LIPIDS 3. Trypsin – enzyme for peptides (#2 for proteins) 4. Pancreatic Amylase –enzyme for starch 5. Nucleases – enzyme for nucleic acids 6. Water

2) Gallbladder connected to LIVER &SI Function – store & send BILE to SI via bile duct Function – store & send BILE to SI via bile duct BILE is NOT an enzyme BILE is NOT an enzyme Helps in physical digestion of LIPIDS Helps in physical digestion of LIPIDS Breaks LIPIDS into smaller particles this is called EMULSIFICATION Breaks LIPIDS into smaller particles this is called EMULSIFICATION Bile is made by liver Bile is made by liver

3)Liver – 6 functions – KNOW!!! B.B.B.B.B.U. 1. Blood Sugar -regulation 2. Blood detoxification 3. Bile production 4. Blood proteins production 5. Blood Cells red broken down 6. Urea - produce

Pancreas – 2 functions 1) exocrine gland – digestive secretions (list 6) 2) endocrine gland – produce hormones insulin & glucagon Role of Insulin & Glucagon Role of Insulin & Glucagon
