front 2 given a volume of 150mL at the end of diastole, a volume of 50 mL @ the end of systole and a heart rate of 60 bpm, the cardiac input is? | back 2 6 liters per minute |
front 3 Which depolarizes next after the AV node? | back 3 AV bundle |
front 4 During the atrial systole what happens? | back 4 atrial pressure exceeds ventricular pressure and the AV valves are open |
front 5 Atrial repolarization coincides in times with? | back 5 QRS wave |
front 6 Soon after the onset of ventricular systolic the? | back 6 AV valves close and the first heart sound is open |
front 7 The base of the heart is it what surface? | back 7 superior |
front 8 In comparing a parallel artery and vein, you would find that | back 8 The artery wall is thicker and artery lumen is smaller |
front 9 Which vessels are bilaterally symmetrical and one vessel of the pair occurs on each side of the body? | back 9 The internal carotid artery and renal vein |
front 10 A stroke that occludes a posterior cerebral artery will most likely affect? | back 10 vision |
front 11 vessels involved in the circulatory pathway to and/or from the brain are? | back 11 brachiocephalic trunk internal jugular vein internal carotid artery |
front 12 which layer of the artery wall thickens most in atherosclerosis? | back 12 tunica intima |
front 13 what is associated with aging? | back 13 increasing blood pressure weakening of venous valves arteriosclerosis |
front 14 an increase in BP would be caused by ? | back 14 increase of heart rate in crease of SV vasoconstriction of the arterioles |
front 15 An increase in BP is not caused by | back 15 hemorrhage |
front 16 The most external part of the pericardium is the? | back 16 fibrous pericardium |
front 17 which heart chamber pumps blood with the greatest amount of force | back 17 left ventricle |
front 18 how many cusps does the right atrioventricular valve have? | back 18 three |
front 19 which layer of the heart wall is an endothelium? | back 19 endocardium |
front 20 What is the location of the heart in the thorax? | back 20 heart is in the mediastinum between the lungs |
front 21 which heart chamber has the thickest wall? what is the functional significance of this structural difference? | back 21 the left ventricle has the thickest wall; this reflex its function, which is to pump blood through the whole body |
front 22 how does the function of the systemic circulation differ from that of the pulmonary circulation? | back 22 pulmonary circulation strictly serves gas exchange. Oxygen is loaded and carbon dioxide is unloaded from the body in the lungs. Systemic circulation provides oxygenated blood to all body organs |
front 23 Why are the heart valves important? | back 23 heart valves keep blood flowing in one direction through the heart |
front 24 why might a thrombus in a coronary artery cause sudden death? | back 24 coronary arteries supply the myocardium (cardiac muscles) with oxygen. If f that circulation fails, the heart fails |
front 25 What is the function of the intrinsic conduction? | back 25 It coordinates the system of the action of the heart chambers and causes the heart to beat faster than it would. |
front 26 to which heart chambers to the terms systole and diastole usually apply? | back 26 left ventricle |
front 27 During isovolumetric contraction of the cardiac cycle, which chambers are relaxing, and which are contracting? | back 27 the atria are relaxing and the ventricles are contracting |
front 28 What causes the lup-dup sounds heard with a stethoscope? | back 28 the operation of the heart valves |
front 29 What does h\the term cardiac input mean? | back 29 co= amount of blood pumped out by each sides of the heart in 1 minute |
front 30 assume you are viewing a blood vessel under the microscope. It has a large lopsided lumen, relatively thick tunica externa, and a relatively thin tunica media. Which kind of blood vessels is this? | back 30 a vein |
front 31 arteries lack valves, but veins have them. How is this structural difference related to blood pressure? | back 31 blood pressure in veins is much lower than that in arteries b/c veins are farther along in the circulatory pathway, hence veins need extra measures to force blood back to |
front 32 How is the structure of capillaries related to their function in the body? | back 32 capillary walls consist of only the innermost intima layer, which is very thin capillaries are the exchange vessels between the blood and tissue cells, these thin walls are desirable |
front 33 In what part of the body are the femoral, popliteal, and articulates arteries found | back 33 lower limb |
front 34 In what part of the body are the axillary, cephalic, and basilic veins located? | back 34 upper limb |
front 35 Which vessel, the hepatic portal vein, hepatic vein, or hepatic artery, has the highest content of nutrients after a meal? | back 35 hepatic portal vein |
front 36 In what two important ways is the pulmonary circulation different from the systemic circulation | back 36 Pulmonary circulation is much shorter and requires a less powerful pump than systemic circulation. Pulmonary arteries carry oxygen-depleted/carbon dioxide-rich blood, whereas the pulmonary veins carry oxygen-rich/carbon dioxide-depleted blood. the opposite is true of the arteries and veins of the systemic circulation. |
front 37 Which artery is palpated at the wrist? at the groin? at the side of the neck? | back 37 radial artery at the wrists; femoral at the groin? as the side of the neck? |
front 38 How does blood pressure change throughout the systemic circulatory pathway? | back 38 It decreases from the heart to the vena cava |
front 39 What is the effect of hemorrhage on blood pressure? Why? | back 39 hemorrhage reduces blood pressure initially because blood volume drops. |
front 40 what contains endothelial cells separated by flap-like valve that can open wide? | back 40 Lymph cap |
front 41 no data | back 41 il |
