Solved in 2 steps
- Different regions of the digestive system specialize in ________ and _________ food and in __________ unabsorbed food residues.Digestion is completed and products are absorbed in the _________. a. mouth b. stomach c. small intestine d. large intestineThe lack of adequate saliva due to the absence of or diminished secretions by the salivary glands is known as zerostomia. _____________________
- The chronic degenerative disease of the liver characterized by scarring is known as serosis. ________________________________Figure 34.19 Which of the following statements about digestive processes is true? Amylase, maltaseT and lactase in the mouth digest carbohydrates. Trypsin and lipase in the stomach digest protein. Bile emulsifies lipids in the small intestine. No food is absorbed until the small intestine.Chemical digestion of proteins is primarily done in the mouth. True False
- The main chemical activity of the stomach is to begin the digestion of carbohydrates. True FalseTRUE OR FALSE: Digestive secretions from the small intestine complete the digestion of carbohydrates, proteins, and lipids. Bacteria in the large intestines produce minerals and nucleic acids.The process by which the products of digestion pass from the lumen of the gastrointestinal tract into the blood or lymph is: absorption defecation digestion peristalsis
- The lining of the GI tract is called the mucosa. True FalseThe following enzymes are involved in carbohydrate digestion in the microvilli, except? sucrase isomaltase amylase trehalaseWhich of the following descriptions is incorrectly matched to the type of digestion occuring? Acidic pH of gastric juice helping break down proteins and activate enzymes - mechanical digestion Salivary amylase breaking down starch - chemical digestion Peristalsis of the small intestine mixing up chyme - mechanical digestion bile salts helping to emulsify fats and raise the pH - chemical digestion chewing and mixing of food in the mouth - mechanical digestion
