front 1 Whether the pulmonary circuit is supplied by both the right and the left sides of the heart | back 1 True |
front 2 Whether the systemic circuit contains oxygen-rich blood only. | back 2 False |
front 3 Given a group of blood vessels, determine which one(s) belong(s) to the pulmonary circuit. | back 3 DO: pulmonary arteries and veins |
front 4 The location of the apex of the heart relative to the midline of the body. | back 4 to the left of the midline |
front 5 The names superior and inferior chambers of the heart. | back 5 superior: R&L Atriums inferior: R&L Ventricles |
front 6 The right atrioventricular valve (tricuspid) regulates the opening between what chambers of the heart | back 6 Right atrium and right ventricle |
front 7 The heart valve(s) through which oxygen-poor blood passes through. | back 7 Tricuspid and pulmonary semilunar valves |
front 8 The valve that regulates the flow of blood between the right ventricle and the vessels leading to the lungs. | back 8 Pulmonary semilunar valve |
front 9 Where in the ventricles the chordae tendineae of the AV valves are anchored to. | back 9 The papillary muscles |
front 10 The inflow of what ions results in the pacemaker potential. | back 10 Sodium (Na+) ions |
front 11 The value of the heart rate if the SA node is damaged. | back 11 Reduced to 40-60bpm |
front 12 The source of the Ca²⁺ needed for myocardial contraction. | back 12 Sarcoplasmic Reticulum |
front 13 The cause of the first sound of the heart | back 13 Closure of AV Valves |
front 14 The cause of the second sound of the heart | back 14 Closure of Semilunar valves |
front 15 Defining the pulse pressure | back 15 difference between systolic and diastolic blood pressure |
front 16 defining the stroke volume | back 16 amount of blood ejected by one ventricle during one contraction. |
front 17 Defining bradycardia | back 17 a heart rate below 60bpm (slow heart rate) |
front 18 defining cardiac output | back 18 volume of blood pumped by one ventricle per minute. |
front 19 The value of blood pressure at the aorta and at the end of the vena cava. | back 19 highest at the Aorta and lowest at the end of the vena cava |
front 20 The effect of cutting the nerve supply to the heart on the heart rate. | back 20 The heart rate would increase to the intrinsic rate of the SA node. |
