1 1. Three Main Functions Chapter 19: General Structure and Function of the Digestive System Digestion-breakdown of food into small particles for transport to blood Absorption- into bloodstream to take to cells Elimination- removal of waste from body 2. Two Groups of digestive organs a. Digestive tract- alimentary canal; tube from mouth to anus (trace the pathway on your diagram sheet) 2. Two Groups of digestive organs b. Accessory organs -organs that assist in digestion; but not part of alimentary canal, ie FOOD DOES NOT GO THROUGH THEM! 4. Organs of the Digestive Tract A. The Mouth - A. also called oral cavity, processes food by:, Ingestion Mastication- (chewing) Deglutition- (swallowing) Incisors for cutting, Cuspids (fangs) for tearing, Molars for grinding; 20 deciduous, 32 permanent (adult) Bolus lump of food that is being swallowed 1. The Teeth 1
2 b. The Pharynx - Also called the throat, connects to esophagus Soft palate-skin at back/top of mouth Uvula- hangs from soft palate & covers sinus when swallowing swallowing animation c. The Esophagus Muscular tube that leads to stomach, lies behind the trachea Hiatal hernia weak diaphragm allows stomach to protrude upward through esophagus animation d. The Stomach - J-shaped pouch that receives food from esophagus 2 sphincters- 1. Lower esophageal sphincter (LES)-top of stomach Pyloric sphincterleads to small intestine 1. Storage of food and liquid during digestion 2. Secrete gastric juice for digestion 3. Secrete mucus while churning 4. Rugae muscular folds allow for expansion 5. Gastric juices hydrochloric acid and pepsin to break down protein 6. Chyme semiliquid mixture that leaves stomach and goes to small intestine ii. FUNCTIONS e. The Small Intestine - 10 foot long structure, about 1 inch diameter, begins with duodenum Function: Absorption of nutrients into bloodstream absorption animation Mesentery thin tissue that holds the small intestine together Greater omentum fatty covering over intestines under peritoneum 2
3 ii. Villi-tiny fingerlike projections provide surface area for absorption 1. blood vessels for absorption of nutrients; Lacteals specialized capillaries that absorb fats f. Large Intestine 5 feet long, 2.5in diameter i. Breaks down undigested food (using e-coli bacteria); ii. Absorbs excess water 4. Accessory Organs for Digestion food doesn t go through them 1. Salivary Glands 3 pairs release saliva a. moistens food and helps with swallowing 2. Liver the body s largest glandular organ Manufactures bile Stores glycogen, Detoxifies harmful substances such as alcohol & drugs Function of the Liver 3. Gallbladder A sac that stores bile for digestion of fats 4. Pancreas - produces insulin for sugar absorption, and bicarbonate to neutralize stomach acid Note: all enzymes are released into common bile duct and then into duodenum 3
4 5. Enzymes and the Digestive Process 1. Enzymes A. Enable food molecules to break apart 2. Water key factor in process of digestion About 7 liters secreted into digestive tract each day Digestion Step by Step Structure Enzymes Released What s broken down Mouth Amylase starch Stomach Hydrochloric acid, pepsin Protein Small intestine intestinal enzymes fats, proteins, Pancreatic enzymes carbohydrates, Bile from liver amino acids Large intestine no enzymes no digestion IV. Absorption the means by which nutrients reach the blood 1. Fats absorbed by lacteals into lymphatic vessels, then digested and returned to blood 2. Vitamins and minerals - absorbed directly into blood from small intestine V. Control of Digestion must be regulated for proper nourishment Nervous by nerves located in intestinal muscle walls Hormonal secretions by digestive organs into blood aid digestion 8. Hunger and appetite Hunger the need for food, regulated by the hypothalamus Appetite desire for food, but not necessarily need; affected by emotions, culture, habits, memory, etc. 9. Eating disorders Eating disorders Anorexia chronic loss of appetite due to variety of issues (drugs, emotions, social) Anorexia nervosa psychological disorder, obsessive desire to be thin 4
5 10. Effects of Aging 1. taste and smell receptors deteriorate leading to loss of appetite 2. Decrease in saliva makes swallowing difficult 3. Digestion slows resulting in chronic constipation 5
