digest it
small intestine - CORRECT ANSWER site of digestion and absorption
large intestine - CORRECT ANSWER reabsorbs water and some vitamins
rectum - CORRECT ANSWER passes undigested foodstuffs from the body
Salivary glands - CORRECT ANSWER releases saliva containing enzymes
liver - CORRECT ANSWER produces bile to breakdown fats
Gallbladder - CORRECT ANSWER stores bile produced by the liver to be released into
the intestine to digest fats
pancreas - CORRECT ANSWER release digestive enzymes to chemically digest food
Accessory GI organs - CORRECT ANSWER salivary glands, liver, gallbladder,
pancreas
True or False. If false, explain why it is false.
Intrinsic factor is a vital glycoprotein produced in the stomach and is necessary for the
B12 to be absorbed. - CORRECT ANSWER True

Compare and contrast insoluble, and soluble fiber. - CORRECT ANSWER Both fiber
forms are complex carbohydrates that are necessary for intestinal health. Insoluble fiber
does not dissolve water and is not broken down by intestinal bacteria. It functions to
increase stool mass and speed passage through the large intestine. In contrast, soluble
fiber dissolves in water, and is broken down by intestinal bacteria. It helps to slow
glucose absorption and fat (thus, lowering cholesterol) and provides satiety to a meal.
