1. Chapter 24 Digestive System

2. Digestive Processes Ingestion Movement / peristalsis Digestion (chemical & mechanical) Absorption Defecation

5. Anatomical Terms Peritoneum (visceral & parietal) Mesentery Falciform ligament Omentum (lesser & greater) Mesocolon

11. 1.Water 2.Solutes 3.Bactericides 4.Amylase

15. Functions 1.Mix gastric juice with food 2.Food reservoir 3.Kills bacteria 4.Breaks down proteins 5.Absorb Vit B12 6.Secretes gastrin into blood 7.Absorbs some small molecules

19. Gastric Digestion Zymogenic (peptic) (Chief) cells = pepsin Parietal (oxyntic) cells = HCl Mucous cells Enteroendocrine cells = gastrin for gastric activities Gastric lipase & rennin

24. Liver Function Carbohydrate metabolism Fat metabolism Protein metabolism Removal of drugs & hormones Excretion of bile Synthesis of bile salts Storage of vitamins, minerals and glycogen Phagocytosis of WBC’s and RBC’s Activation of vitamin D Removal of toxins (includes ammonia) Manufactures heparin

25. Bile Bile consists of water, bile salts, cholesterol, phospholipids, bile pigments and ions. Bile pigment consists of iron, globin, and bilirubin (from the heme). Iron and globin are recycled some bilirubin is excreted in bile.

31. Pancreas Islets of Langerhans produce insulin and glucagon Acini produce pancreatic juice – –Sodium bicarbonate –Amylase –Trypsin –Lipase –Ribonuclease –Deoxyribonuclease

38. Intestinal Juice Water and mucus Maltase, Sucrase and lactase Peptidase Ribonuclease Deoxyribonuclease Lactose intolerance = no lactase
