1. Notes: Accessory Organs (pg 10)

2. Output (pg 11) Paste the diagram on the top of pg 11 Label the stomach, duodenum, and jejunum

3. Liver Largest gland (1.5 kg). Located just below diaphragm. Larger on right side

4. Liver Largest gland (1.5 kg). Located just below diaphragm. Larger on right side 2 major lobes (right and left) and 2 smaller lobes (caudate and quadrate)

5. Liver Largest gland (1.5 kg). Located just below diaphragm. Larger on right side 2 major lobes (right and left) and 2 smaller lobes (caudate and quadrate) Functions: produces bile, stores glucose as glycogen and releases it when blood sugar is too low, detoxifies poisons, excretes waste products in bile, filters the blood (contains phagocytic Kupffer cells)

6. Liver Disease Hepatitis: Inflammation of the liver. Caused by virus. Spread by contaminated food, sexual contact, shared needles

7. Liver Disease Hepatitis: Inflammation of the liver. Caused by virus. Spread by contaminated food, sexual contact, shared needles Cirrhosis: Chronic inflammation causing the liver to become hard and fibrous. Caused by alcoholism and hepatitis

8. Gallbladder Pear-shaped sac attached to the underside of the liver

9. Gallbladder Pear-shaped sac attached to the underside of the liver Stores and concentrates bile

10. Gallbladder Pear-shaped sac attached to the underside of the liver Stores and concentrates bile Delivers bile to the duodenum via the common bile duct

11. Gallbladder Pear-shaped sac attached to the underside of the liver Stores and concentrates bile Delivers bile to the duodenum via the common bile duct Gallstones: If bile becomes too concentrated it can crystalize . Gallstones are very sharp, causing severe pain. Can block bile duct leading to jaundice

12. Output (pg 11) On diagram: Label liver and gallbladder

13. Bile Yellowish-green fluid. Produce about 1 liter per day

14. Bile Yellowish-green fluid. Produce about 1 liter per day Slightly alkaline (pH = 8) so it helps neutralize acidic chyme

15. Bile Yellowish-green fluid. Produce about 1 liter per day Slightly alkaline (pH = 8) so it helps neutralize acidic chyme Contains water, bile salts (emulsifying agents that break large fat globules into tiny droplets), and bile pigments (waste products. Primarily bilirubin from the breakdown of red blood cells)

16. Output (pg 11) Draw diagram of emulsification

17. Pancreas (pg 10) Endocrine and exocrine portions

18. Pancreas (pg 10) Endocrine and exocrine portions Endocrine: Islets of Langerhans secrete insulin and glucagon, which regulate blood sugar

19. Pancreas (pg 10) Endocrine and exocrine portions Endocrine: Islets of Langerhans secrete insulin and glucagon, which regulate blood sugar Exocrine: Makes bicarbonate (neutralizes acidic chyme ) and digestive enzymes and empties them into the duodenum via the pancreatic duct

20. Pancreas (pg 10) Endocrine and exocrine portions Endocrine: Islets of Langerhans secrete insulin and glucagon, which regulate blood sugar Exocrine: Makes bicarbonate (neutralizes acidic chyme ) and digestive enzymes and empties them into the duodenum via the pancreatic duct Pancreatic amylase: Breaks starch into disaccharides

21. Pancreas (pg 10) Endocrine and exocrine portions Endocrine: Islets of Langerhans secrete insulin and glucagon, which regulate blood sugar Exocrine: Makes bicarbonate (neutralizes acidic chyme ) and digestive enzymes and empties them into the duodenum via the pancreatic duct Pancreatic amylase: Breaks starch into disaccharides Trypsin : Breaks proteins into peptides

22. Pancreas (pg 10) Endocrine and exocrine portions Endocrine: Islets of Langerhans secrete insulin and glucagon, which regulate blood sugar Exocrine: Makes bicarbonate (neutralizes acidic chyme ) and digestive enzymes and empties them into the duodenum via the pancreatic duct Pancreatic amylase: Breaks starch into disaccharides Trypsin : Breaks proteins into peptides Peptidase: Breaks peptides into amino acids

23. Pancreas (pg 10) Endocrine and exocrine portions Endocrine: Islets of Langerhans secrete insulin and glucagon, which regulate blood sugar Exocrine: Makes bicarbonate (neutralizes acidic chyme ) and digestive enzymes and empties them into the duodenum via the pancreatic duct Pancreatic amylase: Breaks starch into disaccharides Trypsin : Breaks proteins into peptides Peptidase: Breaks peptides into amino acids Pancreatic lipase: Breaks fats (triglycerides) into monoglycerides

24. Output (pg 11) On diagram: Label pancreas Write a song about the accessory organs. At least 12 lines long. To the tune of a well-known song
