  1. Digestive System By Nate Stemo and Zach Price

  2. Learning Target: Define Digestion

  3. Truth or Baloney? Digestion is the chemical and mechanical breakdown of foods, and the absorption of their nutrients. True

  4. Learning Target: Identify structures of the Digestive System and Function of each

  6. Match Structures of the Digestive System to Their Function Begin mechanical digestion of food • Teeth • Gums • Tongue • Salivary Glands • Pharynx Mixes food with saliva, moves food to pharynx Transports bolus to the esophagus Hold teeth in place Moistens food to aid in swallowing and break down carbohydrates

  7. Match Structures of the Digestive System to Their Function Breaks down lipids, completes digestion • Esophagus • Stomach • Small intestine • Large intestine • Anus Moves bolus by peristalsis Opening through which feces exit digestive tract Mixes bolus with gastric juices to form chyme Removes water from chyme, stores feces

  20. Learning Target: Investigate the role of enzymes in the digestive process

  21. Investigate the role of enzymes in the digestive process Which test tube had the most digestion according to the table? • Cornstarch B) Cornstarch mixed with water C) Cornstarch mixed with saliva

  22. Learning Target: Describe the breakdown of food as it passes through the organs of digestion.

  23. Mouth

  24. Label the diagram of the mouth • Gums 5. 1. 6. • Incisor Hard palate 2. 7. • Molar Soft palate 3. • Palatine tonsils 8. • Uvula 4. • Tongue 9. • Bicuspid Word Bank: Gums, Incisor, Tongue, Soft Palate, Hard palate, Bicuspid, Molar, Palatine tonsils, Uvula

  25. Multiple Choice What is the main function of the mouth? A) Transports bolus to the esophagus B) Starts the mechanical digestion of food C)Digests lipids D) Secretes enzymes Amylase is an enzyme present in our saliva that aids in (carbohydrate/protein) digestion.

  26. Truth or Baloney Baloney Sublingual The parotid gland secretes a primarily mucus type that is thick and stringy. The submandibular gland secretes a more viscous secretion than the parotid gland. Saliva secretion is regulated by the cardiovascular system. True Baloney Nervous

  27. Truth or Baloney Baloney Is chewed and mixed with saliva Bolus is the name of food once it enters the small intestine. The pharynx prevents food from entering the respiratory system. Muscular waves that aid in food traveling through the esophagus are called peristalsis. Baloney Layrnx True

  28. Stomach

  29. Label the diagram of the stomach 6. • Fundic region 1. 7. • Cardiac region 2. • Body region 8. 5. 9. 3. • Pyloric Canal • Pyloric region 4. Word Bank:Fundic region, Cardiac region, Pyloric region, Body region, Esophageal Sphincter , Rugae, Pyloric Canal, Pyloric Sphincter, Esophagus

  30. Match Structures of the Digestive System to Their Function Exit region of the stomach • Cardiac region • Fundicregion • Body region • Rugae • Pyloric region Entrance region of the stomach Main part of the stomach Temporary storage area Folds that provide friction and increase surface area

  31. Multiple Choice What is the function of the stomach? A)Mixes bolus with gastric juices B) Forms chyme C) Breaks down proteins D) All of the above The mechanical digestion that takes place in the stomach is? A) Digesting carbohydrates B) Making chyme C) Mixing the bolus and gastric juice D) All of the above

  32. Fill in the Blank The parietal cells secrete ________. The chief cells secrete____________. Mucous cells secrete________ to protect your stomach lining. Word Bank Mucus pepsinogen HCl

  33. Multiple Choice What is the function of the stomach? A)Mixes bolus with gastric juices B) Forms chyme C) Breaks down proteins D) All of the above

  34. Fill in the Blank HCl converts __________ into __________, which is the most important digestive enzyme because it digests __________ in the stomach. Word Bank pepsin pesinogen carbohydrates proteins

  35. Truth or Baloney Baloney Proteins Lipids begin to be digested in the stomach. Pepsin could not be formed if there was no HCl in the stomach. Food in the stomach is now called bile. True Baloney Chyme

  36. Order the biochemicals in order from first digested to last digested • 3 ___. Protein ___. Lipid ___. Carbohydrate ___. Water • 4 • 2 • 1

  37. Small intestine

  38. Label the diagram of the small intestine • Pyloric sphincter 1. • Duodenum 2. • Jejunum 4. • Ilium 3. Word Bank: Jejunum, Duodenum, Ilium, Pyloric Sphincter

  39. Truth or Baloney True The small intestine completes the process of digestion. The mesentery is a layer of connective tissue that supports the small intestines The small intestine is very long because it needs to absorb the nutrients from the chyme. True True

  40. Fill in the Blank The pancreas secretes (Bicarbonate/Hydrogen) ions to neutralize the chyme. Which of the following is not a function of the lobes of the liver? A.) Metabolize carbohydrates, fats, and proteins B.) Reduce acidic levels of the chyme C.) Store vitamins D.) Detoxify the body (CCK/Bile) is secreted by the gall bladder that helps digests lipids.

  41. Multiple Choice Which body system controls the secretions of the pancreas and gallbladder? A) Nervous B) Endocrine C) Respiratory D) Digestive

  42. Match enzymes with there functions Breaks fats into glycerol and fatty acids • Pancreatic amylase • Lipase • Trypsin Converts polypeptides into amino acids Breaks maltose into glucose

  43. Multiple Choice Which structure increases the surface area of the small intestine for absorption? A)Chief cells B) Villi C) duodenum D) Serosa What percent of consumed nutrients are absorbed through the small intestine A)65% B)75% C)85% D)95%

  44. Truth or Baloney Blood capillaries transport the nutrients throughout the body. True

  46. Label the diagram of the large intestine 1. 4. 2. 5. 3. 6. 7. Word Bank: anal canal, rectum, sigmoid colon, descending colon, ascending colon, transverse colon, cecum,

  47. Match Structures of the Digestive System to Their Function Stores feces until defecation • Cecum • Colon • Rectum • Anal Canal Last stop for feces Receives chyme from the small intestine Absorbs water from chyme

  48. Truth or Baloney Absorb water and electrolytes from chyme Two functions of the large intestine are forming and storing feces as well as secreting trypsin. Bacteria in the large intestine synthesize vitamins and molecules the human digestive system cannot. Baloney True

  49. Learning Target: Describe the process of feces formation.

  50. Learning Target: Describe the process of feces formation.True or False The name of the chyme once the water has been absorbed out of it is called Feces. True
