Digestion Unit Day 6 The quality of our expectations determines the quality of our actions. Andre’ Godin Today’s Agenda Recap what we’ve done in this unit so far. Notes On Objectives 11-14 Small Intestine and large intestine notes Small intestine lab Obj. 1: Alimentary Canal The continuous hollow tube that extends from the mouth to the anus Permanent Teeth 32 teeth, start erupting by 6-7 yrs old Dental Formula: Right Left 2I, 1C, 2PM, 3M X 2 = 32 teeth 2I, 1C, 2PM, 3M Incisors, Cuspids, Bicuspids, Molars The Stomach How is the stomach designed to do its job? Name the 3 different phases of stomach regulation and how each effects hunger. What is in gastric juice? Obj. 10 Regulation Cephalic phase- sight, smell Gastric phase-stomach distension and pH Intestinal phase-food reaches small intestine, stimulates Can you name 3 accessory organs? Functions of the Liver Produces bile and other digestive LIVER ANDenzymes BILIARY TRACT SLIDES Function of Gall Bladder Stores and releases bile Pancreas—creates digestive enzymes Objective 11: Absorption in the small intestine Complete the handout entitled “Digestion in the the small intestine” to cover the information as to how nutrients are absorbed in the small intestine. What are the regions of the Small Intestine? What are the regions of the Small Intestine? Duodenum Jejunum Ileum Obj. 11 Write these on the back of the note page. Functions of the Small Intestine Mixes chyme with bile, pancreatic juice, and intestinal juice Propels food to the large intestine Functions of the Small Intestine Digestion of: and Absorption Carbohydrates Proteins Lipids Nucleic Acids Nutrients are actively transported from microvilli to the bloodstream: Antacid Lab Hand out the makeup version Obj. 12 Role of Bile & Bicarbonate Ions in Pancreatic Juice Bile: Emulsify Fats Turns chyme brown Bicarbonate Ions Neutralizes the acidic chyme Obj. 12: Role of bile, bicarbonate ions in pancreatic juice Bile: Fuction: Emulsifies lipids Obj. 13 Regulation of Pancreatic Juices Function of the Pancreas A gland that produces many digestive enzymes and bicarbonate Obj. 14: Structure & Function of Large Intestine Functions include: a. Absorption of water b. Absorption of electrolytes c. Absorption of vitamins (B&K) made by bacteria d. Defecation Obj. 14 (cont.) Defecation is triggered by feces entering the rectum. The walls of the rectum contract to move stool. Movement is aided by the Valsava maneuver. In this maneuver we close the glottis, contract the diaphragm and abdominal walls to create pressure distally. Small Intestine Lab Activity
