1 Chapter 20 The Digestive System Exam Study Questions 20.1 Overview of GI Processes 1. Describe the functions of digestive system. 2. List and define the four GI Processes: 20.2 Functional Anatomy of the GI System Figure 1 Digestive System 1. Match digestive processes and major components. Some letters may be used more than once. 1) Peristalsis occurs at. 2) Chewing and ingestion occur at 3) Swallowing occurs at. 4) Segmentation occurs at 5) Haustration and mass movement occurs at. 6) Migrating motility complex occurs at 7) Secretion of bile. 8) Secretion of acid, IF, histamine and pepsinogen. 9) Secretion of mucus. 10) Secretion of gastrin 11) Secretion of CCK, secretin and GIP 12) Major food digestion and absorption occur at. 13) Movement of food does not occur at. 14) Additional absorption of water, salt, vitamins B complex and K occurs at 1
2 2. Use Figure 1 to match functions of digestive components (Table 20.1). Letter(s) Functions The accessory gland that secretes pancreatic juice. The accessory gland that secretes bile; metabolic processing of nutrients; removal of aged RBCs; elimination waste; manufacture plasma protein; storage of macromolecules, secretion, modification, and metabolizing of hormones. Transport food from mouth from mouth to esophagus. Control of defecation Mechanical breakdown food and initial digestion of starch and lipids with salivary enzymes. Major site of food digestion and absorption; secretion of hormone and bicarbonate Mechanical breakdown food, secretion of protein digestion enzymes and hormones; food storage Storage feces Conduction of food from pharynx to stomach of water and electrolytes, synthesis vitamin; form feces Secretion of saliva Storage bile Accessary glands 3. How does the stomach protect itself from self-digestion? 4. What does hepatic portal system do? 2
3 5. Compete the table (pages ) Carbohydrates Location of Major Digestion Form of Location of Mechanism of Lipids Proteins 6. The final digestion of carboxylates is accomplished by enzymes (CD EX). 7. Pancreatic is responsible for the majority of fat digestion (CD EX). 8. of sodium is coupled with the absorption of (page 586). 9. Potassium ions, and bicarbonate ions are (active/passive) absorbed in small intestine (page 587). 10. Water is reabsobed by s. 11. The absorption of iron, calcium and vitamin B 12 all require the help of a (page 587). 12. Colic bacteria provide substantial quantity of as a byproduct of their metabolism (CD EX) General Principles of GI Regulation 1. Describe the long reflex pathway of neural regulation of the digestive system. 2. Describe the short reflex pathway of neural regulation of GI function. 3. Describe the three phases of gastric intestinal control. 4. Increased parasympathetic activity (enhances or decreases) GI activity while depresses digestive functions 5..What is the function of leptin? 6. What are sateity factors? 3
4 7. What are oxrexigenic factors? 8. Indicate which hormone(s) is being described by writing the name in the blank. The choice of hormones includes CCK, secretin, gastrin, GIP (Table 20.2 and CD Ex page 3). The name can be used more than once. Some description may be true for more than one hormone. 1) secreted by the pyloric gland area. 2) These hormones are secreted in duodenum and jejunum. 3) The release of is stimulated primarily by the presence of fat (fatty acids) or protein. 4) The presence of acid in duodenum stimulates the secretion of 5) inhibit(s) gastric secretion and gastric motility. 6) stimulates gastric secretion and motility in response to distension of the stomach. 7) simulates pancreatic bicarbonate secretion (and enzyme secretion to a lesser extent) 8) stimulates relaxation of the sphincter of Oddi and release bile into small intestine. 9) stimulates insulin secretion in the presence of glucose, fats or acid or distension of duodenum. 9. Indicate which digestive secretion is being described in each question by writing the appropriate terms in the blank using bile salt, pepsin(ogen) amylase, lipase and trpsin(ogne) 1) Pancreatic enzyme that digests protein. 2) Gastric enzyme that digests protein. 3) Enzyme that digests fat. 4) Secreted by the salivary glands and pancreas. 5) Forms micelles to aid fat absorption. 6) Activated by HCl. 10. Digested peptides and carbohydrates enter the blood of the system 11. The final digestion of carbohydrates is accomplished with enzymes (CD Ex page 8). 12. Digestive reflexes originated in the CNS are called 13. Short reflexes of the digestive system are integrated in 20.5 GI Secretion and Its Regulation 1. Saliva secretion is regulated by the center (p590). 2. What do these cells secrete? 1) parietal cell: 2) chief cell: 4
5 3) paracrine cell: 4) mucus neck cells 5) G-cells: 3. Gastric secretion of acid and pepsinogen is controlled by a. Cephalic, gastric and intestinal- phase b. Neural reflex c. Hormones d. All of these 4. The secretion of pancreatic juice is controlled by (page 592) 5. The secretion of bile is stimulated by hormones and (p593) GI Motility and Its Regulation 1. The process by which food is received into the GI tract via the mouth is called (CD Ex). 2. Motility in the mouth is. Functions are ; and (CD EX) 3. Motility in esophagus is. initiates primary peristalsis in esophagus. Function is to propel food bolus into the (CD EX). 4. (T/F) Swallowing has both voluntary and involuntary components (CD EX) 5. The motility of the stomach includes and (CD Ex). 6. During the inter-digestive period, occur about once every 90 minutes to move undigested materials toward the terminal ileum (CD EX). 7. Migrating motility complexes are controlled by the central nervous system (T/F) 8. What are the functions of segmentation (CD Ex)? 9. Large intestine motility during the inter-digestive period is called. Its function is to absorb and.(cd Ex) 10. Large intestine motility during a meal is called. It function is to. (CD EX) 11. What is the function peristalysis? 12. (True/False). Neural and hormonal activity generally affects the force of contraction rather than the frequency of slow wave in gastrointestinal smooth muscle. 13. The hormone causes the ileocecal sphincter to relax during the gastric phase (CD EX). 14. Migrating motility complexes are controlled by the nerve system (CD EX). 15. The reflex stimulates mass movement of colon (CD EX). 16. The vomiting reflex is coordinated in the (CD EX). 5
