Canines • Digestion CLF
12. What are the six nutrients needed in the body?
• minerals • water • fats • vitamins • carbohydrates • proteins • WKST Final digestion and absorption
13. What happens after chyme enters the small intestine?
After chyme enters the small intestine, the acidic chyme is neutralized by the basic intestinal juices. • WKST Final digestion and absorption
15. What process takes place in the large intestine?
Water is absorbed from digested food • Digestion CLF
19. The process by which nutrient molecules pass through the wall of the digestive system and into the bloc is called what?
Absorption • WKST Final digestion and absorption
21. Where is the most amount of water absorbed in the body?
Large intestine • Digestion CLF
24. What substance coats and protects the inside of the stomach?
Mucus • WKST Final digestion and absorption
31. The process by which waste is eliminates is called what?
Defecation • Digestion CLF
34. What is the main structure of the tooth and where is it?

37. One of the roles of the _________ is to prepare waste material for elimination
Large intestine • Digestion CLF
39. In what part of the body does bacteria make vitamin K?
Large intestine • WKST Final digestion and absorption
40. The breakdown of complex food molecules into simpler molecules is what kind of digestion?
Chemical • WKST Final digestion and absorption
41. Water from the digestive system is absorbed into what intestine?
Large intestine • Digestion CLF
42. Chemical reactions in the body take place in what nutrient?
Water • WKST Final digestion and absorption
46. What is the liver and where is it located?
Located right above the gallbladder and it is the largest internal organ in the human body • Digestion CLF
48. What is the gallbladder and where is it located?
Located to the left of the pancreas and it is organ that stores bile until it is needed in the small intestine. • Digestion CLF
49. What is the small intestine and where is it located?
Location- lines around/inside the large intestine and this organ is where food is digested and nutrients are absorbed • Digestion CLF
#50. Define these terms: Duodenum Pancreas Small intestine
-the first part of small intestine leading to jejunum -produces hormones and makes enzymes that aid digestion Without those enzymes, chemical digestion could not be completed -where food is digested and nutrients are absorbed This organ would be unable to absorb small nutrient molecules into the bloodstream • Digestion CLF
51. What is the name of the organ in which food is absorbed?
Small intestine • Digestion CLF
#52. Define these organs- Esophagus Stomach Pancreas Rectum Small intestine Large intestine Liver
• help carry food down to the stomach by muscle contractions • holds food and releases it bit by bit into the small intestine. This organ also secretes hydrochloric acid, which kills dangerous bacteria • produces hormones and makes enzymes that aid digestion • holding station for waste products, known as feces • where food is digested and nutrients are absorbed • where water is absorbed from digested food • where bile is produced and receives all absorbed nutrients from the gut • Digestion CLF
53. What is the large intestine and small intestine, and how do they compare in size?
-where water is absorbed from digested food -where food is digested and nutrients are absorbed The first organ is shorter and larger in diameter than the second one • Digestion CLF
54. What is peristalsis?
Involuntary waves of muscle contraction • WKST Final digestion and absorption
56. Which two organs in the digestive system do not have food traveling through them?
Pancreas and liver • Digestion CLF
