front 1 Match the following digestive processes with the correct description | back 1 Mechanical Digestion – Chewing, mixing, churning and segmentation of food Defecation – Elimination of indigestible solids Chemical Digestion – Enzymatic degradation of foodstuffs into simpler molecules Absorption – Passage of digested materials from the lumen of the GI tract into the blood or lymph Ingestion – Taking food into the digestive system |
front 2 What is the consequence of obstruction of the lymphatics | back 2 Obstruction of the lymphatics results in edema distal to the obstruction. |
front 3 Children born without a thymus must be kept in a germ-free environment if they are to survive. Explain why this is necessary. | back 3 If the thymus fails to develop, the T cells will not mature and become immunocompetent. If T cell function is disrupted, there is no resistance to disease. |
front 4 What are some of the drawbacks of passive humoral immunity? | back 4 The effects are short lived; it does not trigger memory cell production; and your body degrades the antibodies. |
front 5 Which of the following would not be classified as a lymphatic structure? | back 5 pancreas |
front 6 The thymus is most active during: | back 6 childhood. |
front 7 The lymphatic capillaries are: | back 7 more permeable than blood capillaries. |
front 8 Peyer's patches are found in the: | back 8 small intestine |
front 9 The tonsils located at the base of the tongue are the | back 9 lingual tonsils. |
front 10 Which of the following is associated with passive immunity? | back 10 passage of IgG antibodies from a pregnant mother to her fetus |
front 11 Which of the following is not a function of the inflammatory response? | back 11 replaces injured tissues with connective tissue |
front 12 the system that recognizes foreign molecules and acts to immobilize, neutralize, or destroy them is the: | back 12 immune system |
front 13 Interferons: | back 13 interfere with viral replication within cells |
front 14 The system that recognizes foreign molecules and acts to immobilize, neutralize, or destroy them is the: | back 14 immune system |
front 15 Which of the following is characteristic of complete antigens? | back 15 reactivity with an antibody |
front 16 Innate immune system defenses include | back 16 phagocytosis. |
front 17 Select the correct statement about active and passive immunity. | back 17 Active and passive humoral immunity are both mechanisms of specific immunity that use antibodies. |
front 18 Immediate hypersensitivities: | back 18 include anaphylaxis, triggered by a second (or later) exposure to an allergen to which the individual has been sensitized. |
front 19 Select the correct statement about antigens. | back 19 type II diabetes |
front 20 The chemical and mechanical processes of food breakdown are called: | back 20 digestion. |
front 21 The absorptive effectiveness of the small intestine is enhanced by increasing the surface area of the mucosal lining. Which of the following accomplish this task? | back 21 plicae circulares and intestinal villi |
front 22 The ducts that deliver bile and pancreatic juice from the liver and pancreas, respectively, unite to form the: | back 22 hepatopancreatic ampulla. |
front 23 The terminal portion of the small intestine is known as the: | back 23 ileum. |
front 24 Which of the following is not characteristic of the large intestine? It: | back 24 is longer than the small intestine. |
front 25 A baby is admitted to the hospital with a history of projectile vomiting after each feeding. On examination, it is found that the sphincter controlling food passage from the stomach to the duodenum is thickened and does not open readily. Because of the baby's loss of gastric juice, his blood probably indicates: | back 25 alkalosis. |
front 26 When a person's hypothalamic thermostat is set to a higher level and the actual body temperature is below that level, the person may: | back 26 shiver |
front 27 When the lymphatics are blocked due to tumors, the result is: | back 27 severe localized edema distal to the blockage. |
