1 The Digestive Process Begins Final Digestion and Absorption The Digestive Process Begins Final Digestion and Absorption Dissection or Mixed Bag

2 List the three major kinds of teeth we have. What kind of digestion do they perform? 100

3 Incisors, canines, molars. 100

4 Explain the difference between mechanical and chemical digestion. 200

5 Mechanical digestion is the physical break down of food. Chemical digestion is when chemicals in the body are used to break down foods into their smaller chemical building blocks. 200

6 How does the body keep food from going down the “wrong pipe”? 300

7 There is a flap of tissue called the epiglottis that seals off your trachea as you swallow food. 300

8 Define enzyme. 400

9 An enzyme is a protein that speeds up chemical reaction in the body. 400

10 How does an ulcer form? 500

11 In many cases, a bacteria called H. pylori weakens the mucus layer of the stomach as it lives just below the mucus layer. Stomach acid then can damage the sensitive lining of the stomach. 500

12 Approximately how long is the small intestine? 100

13 6 meters 100

14 200 What’s the function of the rectum?

15 It’s function is to compress waste into solid form. 200

16 What’s the benefit of bacteria located in the large intestine? 300

17 As they feed on the material in the large intestine, they produce vitamins for the body to use.

18 Explain specifically how fiber helps the digestive system. 400

19 Fiber helps thicken the material in the small intestine, which then allows peristalsis work effectively. 400

20 Explain the relationship between diarrhea and the function of the large intestine. 500

21 Diarrhea is a condition when the waste material in the large intestine contains too much water. A function of the large intestine is to absorb the appropriate amount of water from waste material.

22 What are the two types of digestion? 100

23 mechanical and chemical 100

24 What is the muscular tube that connects the mouth to the stomach called? 200

25 esophagus 200

26 What are the involuntary waves of muscle contraction called that occur in the esophagus, stomach and other areas of the digestive system? 300

27 peristalsis 300

28 What are the two components of digestive juice? 400

29 pepsin and hydrochloric acid 400

30 500 What substance do the cells in the stomach produce to protect the stomach lining?

31 500 mucus

32 Where in the digestive system does nearly all of the chemical digestion take place? 100

33 small intestine 100

34 What are the millions of tiny finger-shaped structures that absorb nutrient molecules called? Where are they found? 200

35 villi (villus – singular) They are found in the small intestine. 200

36 What is the function of bile? 300

37 Bile physically breaks up fat particles into smaller fat droplets so they can next be broken down by enzymes produced in the pancreas. 300

38 What major role does the pancreas play in digestion? 400

39 The pancreas produces enzymes that flow into the small intestine and help to break down starches, proteins, and fats. 400

40 In what part of the digestive system is Vitamin K produced? How is it produced? 500

41 large intestine The large intestine contains bacteria that produce certain vitamins, such as Vitamin K. 500

42 What is absorption (be very specific)? Why is it important? 100

43 Absorption is the process of passing nutrients through the walls of the digestive system into the bloodstream. Absorption is important in transporting nutrients to all the parts of the body. 100

44 What was the largest (non-hollow) organ found inside the body? 200

45 liver 200

46 What are the 3 functions of the digestive system? 300

47 1.Breaks down food into molecules for use. 2.Molecules absorbed into blood and carried throughout the body. 3.Wastes eliminated from body. 300

48 How long is the entire digestive system? How long is the small intestine? How long is the large intestine? 400

49 All – 9 meters Small – 6 meters Large – 1.5 meters 400

50 Why does a chewed up Saltine cracker breakdown starch into glucose more quickly than a hand- crumbled Saltine cracker? 500

51 Saliva produces an enzyme called amylase that breaks down starch into glucose. 500

52 FINAL JEOPARDY The Digestive System

53 List the progressive order of the following terms from start to end of digestion: villi, rectum, pepsin, incisor, epiglottis, water absorption, salivary gland

54 incisor salivary gland epiglottis pepsin villi water absorption rectum
