1 of 25What lymph organ(s) filter lymph?Lymph nodes and the spleenLymph nodes, the thymus, and the spleenOnly the lymph nodesTonsils, thymus, and the spleenOnly the spleenQuestion2 of 25What is the function of the lymphatic vessels?Remove excess fluid from blood vessels and send it to the cardiovascular system for recirculationRemove excess fluid from body tissues and send it to the kidneys for removalRemove excess fluid from blood vessels and send it to the kidneys for removalRemove excess fluid from the cardiovascular system and send it to the lymph nodesRemove excess fluid from the body tissues and send it to the cardiovascular system for recirculationQuestion3 of 25Which of the following describes the flow of lymph through the lymph nodes?Lymph enters only one lymph node before entering the cardiovascular system.Lymph flow is fast and under great pressure.Lymph flows through sinuses in a slow manner.Lymph flows through the efferent vessels and then into the sinuses.Lymph flows slowly from the cardiovascular vessels into the hilum.Question4 of 25What are the two major collecting vessels that drain into the subclavian vein?Right lymphatic duct and thoracic ductLeft lymphatic duct and thoracic ductSubclavian lymphatic duct and thoracic ductThoracic duct and cervical ductSubclavian lymphatic capillaries and right lymphatic ductQuestion5 of 25Which of the following is a function of the lymph nodes?To remove foreign substances.To mix the lymph with circulating blood.To dilute the lymph.To produce lymph.To suppress the immune response.Question6 of 25Which of the following is a nonspecific defense that kills virus-infected body cells?PhagocytesSkin and mucous membranesNatural killer cellsFeverInflammationQuestion7 of 25What is the function of the thymus gland?To trap and remove debris from entering the throat.To produce hormones that program lymphocytes.To trap and remove debris from the digestive tract.To filter lymph.To filter the blood of debris.Question8 of 25What organ is responsible for the removal of destroyed red blood cells from the blood?SpleenThymusPeyer’s patchesAppendixTonsilsQuestion9 of 25Which of the following is an adaptive body defense?Mucous membranesFeverInflammatory responsePhagocytosisAntibody productionQuestion10 of 25What are interferons?Large molecules secreted by the endothelium that attract neutrophils to the area of invasionSmall proteins produced by cells infected by viruses that travel to nearby uninfected cellsChemicals secreted by bacteria that activate the immune responseA plasma protein that attaches to a foreign cell and produces lesion on that cell’s surfaceA chemical released by injured cells that causes blood vessels to dilateQuestion11 of 25What is the function of plasma cells?To produce plasma.To activate the T cells.To activate the B cells.To enable the body to respond to a second infection.To produce specific antibodies.Question12 of 25What type of immunity is used when a patient is given an oral antibiotic for a bacterial infection?Active humoral immunityPassive humoral immunityCellular immunityInnate adaptive immunityPassive innate immunityQuestion13 of 25What is the inflammatory response?A process that begins when antibodies attack specific antigensA nonspecific response as a result of a high feverA process that releases interferon to fight virus infected cellsA nonspecific response when body tissues are injuredA specific humoral response to body tissue damageQuestion14 of 25Which of the following describes macrophages?They originate in the thymus.They become immunocompetent in various places in the body.They produce antibodies.They phagocytize foreign debris.They can differentiate into plasma cells.Question15 of 25Which of the following is associated with the inflammatory response?Abnormally high body temperatureDamage to the nervesSpread of pathogens to other areasIncreased permeability of the capillariesAdaptive immune responseQuestion16 of 25Which of the following describes a fever?Fever is a specific response to a specific antigen.Fever is an elevated body temperature due to inflammation.Fever is an innate body defense.Fever decreases the metabolic rate of tissues.Fever results in calcium uptake in the liver which limits the amount available for bacteria.Question17 of 25Which antibody class is the most abundant in the body?IgAIgDIgEIgGIgMQuestion18 of 25Organ transplants involving a recently deceased body are an example of what type of transplant?AutograftIsograftAllograftXenograftImmunograftQuestion19 of 25What is the purpose of immunosuppressive therapy?Prevention of the production of histamine in allergy sufferersPrevention of rejection after an organ transplantIncreasing the activity of helper T cells in AIDS patientsIncreasing the immune protection for patients with melanomaPrevention of anaphylactic shockQuestion20 of 25Which of the following describes basic antibody structure?Antibodies consist of two amino acid chains.The chains are linked together by disulfide bonds.The general shape is a double helix.Four heavy chains make up the constant region.Two light chains bind with four heavy chains.Question21 of 25What is an immunodeficiency disease?When the production of immune cells or complement is abnormalWhen the immune response is abnormally vigorousWhen the body produces antibodies that attack its own body cellsWhen the body produces too many lymphocytesWhen the body rejects a transplanted organQuestion22 of 25What is the function of the helper T cell?It produces antibodies.It binds with a specific antigen and stimulates the production of other immune cells.It is a descendant of an activated B or T cell that stays in the body for years after the initial infection.It resides in the lymph nodes and evolves into a plasma cell.It engulfs and digests antigens and then presents parts of the antigen on its plasma membrane.Question23 of 25The transplant of a heart valve from a pig is an example of what type of transplant?AutograftIsograftAllograftXenograftImmunograftQuestion24 of 25Which autoimmune disease is associated with impaired communication between neurons and skeletal muscles?Rheumatoid arthritisMultiple sclerosisGrave’s diseaseMyasthenia gravisSystemic lupus erythematosusQuestion25 of 25What substance triggers the symptoms associated with hypersensitivity or an allergic reaction?HistamineAcetylcholineThyroid hormoneVirusesAntibodies
