front 1 The respiratory mucosa is | back 1 Pseudostratified cilated columnar epithelium |
front 2 The upper respiratory system consists of all the following except | back 2 larynx |
front 3 Functions of the nose are all of the following except | back 3 none of the above (functions include: warms the air, humidfies the air, filters the air) |
front 4 Bronchial tree consists of | back 4 -primary bronchi -secondary bronchi -bronchioles |
front 5 The bronchioles | back 5 control of airflow resistance and or distribution in the lungs. |
front 6 Boyle's law | back 6 for a gas in a closed container and at a constant temperature, pressure is inversely proportional to volume |
front 7 Cellular respiration | back 7 is the intracellular reaction of O2 with organic molecules to produce CO2, water, and ATP |
front 8 External respiration is subdivided into the following integrated processes except: | back 8 Exchange of gases between blood and the lungs |
front 9 Dalton's Law | back 9 each of the gases contributes to the total pressure in proportion to its relative abundance |
front 10 Gas exchange at the respiratory membrane is efficient for the following reasons except | back 10 the total surface area is small |
front 11 Local vasodilators accelerate blood flow in response to | back 11 decreased temperature |
front 12 Kinins | back 12 cause contraction of visceral smooth muscle, but they relax vascular smooth muscle via NO, lowering blood pressure |
front 13 Inhibits platelet aggregation and promotes vasodilation | back 13 prostacyclin |
front 14 The chordae tendonae and papillary muscles play important roles in the normal function of the AV valves. | back 14 true |
front 15 The factors that affect tissue perfusion are all the following expcept | back 15 autoregulation |
front 16 monitor the degree of stretch in the walls of carotid and aortic sinuses | back 16 baroreceptors |
front 17 Theories of autoregulation are the following except | back 17 temperature theory |
front 18 The P wave | back 18 accompanies the depolarization of the atria |
front 19 Phases of the cardiac cycle | back 19 -atrial systole -atrial diastole -ventricular systole -ventricular diastole |
front 20 The atrioventricular (AV) valves prevent backflow of the blood from the ventricles to the atria when the ventricles are contracting. | back 20 true |
front 21 Cardiac output is the amount of blood pumped by the left ventricle in one second | back 21 false |
front 22 Isovolumetric contraction period | back 22 lasts approximately 270 msec |
front 23 Ventricular conducting cells consist of the AV bundle, bundle branches, and | back 23 Purkinje fibers. |
front 24 Connective tissue fibers of the heart function to do the following except | back 24 stabilizes the heart valves |
front 25 There are two atrioventricular valves | back 25 bicuspid (mitral), tricuspid |
front 26 End diastolic volume is | back 26 130 |
front 27 S2 is caused by the | back 27 closing of the semilunar valves |
