- Figure 16.7 Which of the following statements about the digestive system is false? a. Chyme is a mixture of food and digestive juices that is produced in the stomach. b. Food enters the large intestine before the small intestine. c. In the small intestine, chyme mixes with bile, which emulsifies fats. d. The stomach is separated from the small intestine by the pyloric sphincter.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.Figure 34.11 Which of the following statements about the digestive system is false? Chyme is a mixture of food and digestive juices that is produced in the stomach. Food enters the large intestine before the small intestine. In the small intestine, chyme mixes with bile, which emulsifies fats. The stomach is separated from the small intestine by the pylloric sphincter.
- Figure 34.12 Which of the following statements about the small intestine is false? Absorptive cells that line the small intestine have microvilli, small projections that increase surface area and aid in the absorption of food. The inside of the small intestine has many folds, called villi. Microvilli are lined with blood vessels as well as lymphatic vessels. The inside of the small intestine is called the lumen.Intrinsic factor, found in the lining of the stomach, is needed to? Stimulate the release of bile from the pancreas Absorb vitamin B12 Stimulate the production of digestive enzymes in the liver All of the above.The regulation of the gastrointestinal response is done via which of the following? Hormonal interactions Neural interactions Hormonal and neural interactions Neural and electrical interactions
- In cases of extreme emergency when the upper air passageway is blocked by a foreign object to the extent that the victim cannot breathe, quick reaction is required to save the person's life What procedure is designed to force such an object out of the air passage by the sudden application of pressure to the abdomen? O Heimlich maneuver O Leopold's maneuver O Cardiopulmonary resuscitation O Valsalva maneuver 50 51 52 53 54 55 56 57 58 59Which of the following components of digestion is responsible for the chemical breakdown of foods? Group of answer choices Chewing Enzymatic hydrolysis Dissolving EmulsificationWhich of the following statements is TRUE? Hydrochloric acid makes an acidic environment in the stomach that promotes promotes polysaccharide digestion. Lipase, produced by the pancreas, digests the emulsified fats into fatty acids. Bile, synthesized by the liver and stored in the gall bladder, digests fats which will then be absorbed in the small intestine The acidic environment converts the inactive pepsin into its active form: pepsinogen. Pepsinogen digests proteins in the stomach.
- In order for the food to be processed and absorbed in an optimal way, there are several feedback mechanisms. One of the most important starts when the food reaches the small intestine, this is sometimes also called the intestinal phase. Describe what happens if the food that reaches the duodenum contains a lot of fat and a lot of protein Which different signaling pathways (including the signaling substances involved) control the different gastric emptying,hydrochloric sekretion that are affected by the respective stimuli.Regarding the functions of the gastrointestinal system, match each term with the phrase that best describes or defines it an enzyme found in saliva and intestinal secretions that breaks down carbohydrate molecules like starches Lipid deposits in the non-adipose compartment of the body, a risk factor for chronic disease regardless of weight A prebiotic - a non-digestible oligosaccharide that provides nourishment for beneficial organisms in the gut A strain of bacteria that's very common in the human gut [Choose ] [Choose ] Bacteroidetes Amylase Lipase Salmonella Brown Fat Inulin Ectopic Fat [Choose] [Choose ]Individuals who are lactose intolerant do not produce enough of the enzyme in the to properly digest lactose.
