  1. Compared to the right ventricle the left ventricle does not
    1. have thicker myocardium
    2. pump blood through more miles of blood vessels
    3. generate greater pressure
    4. pump more blood per minute

  2. The atrioventricular (AV) node and atrioventricular bundle are part of the
    1. conduction system that stimulates the heart electrically
    2. coronary circulation that carries blood through the heart
    3. pulmonary circuit which allows blood to become oxygenated
    4. heart valve system that improves the efficiency of heart function

  3. When closed, the semilunar valves prevent backward flow from the _?_ to the _?_.
    1. atria to the ventricles
    2. ventricles to the atria
    3. arteries to the ventricles
    4. ventricles to the arteries

  4. Which statement is incorrect?
    1. the superior vena cava is connected to the right atrium
    2. the pulmonary veins are connected to the left atrium
    3. the inferior vena cava is connected to the right ventricle
    4. the aorta is connected to the left ventricle

  5. In a normal cardiac cycle
    1. the ventricles are in systole for approx. 0.3 second and in diastole for approx. 0.3 second
    2. the ventricles are in systole for approx. 0.3 second and in diastole for approx. 0.5 second
    3. the ventricles are in systole for approx. 0.5 second and in diastole for approx. 0.3 second
    4. the ventricles are in systole for approx. 0.5 second and in diastole for approx. 0.5 second

  6. During most of diastole,
    1. the ventricles are expanding in size
    2. the pressure in the ventricles is low
    3. the atrioventricular valves are open
    4. the ventricles are filling with blood
    5. all of the above

  7. The two major heart sounds are caused by
    1. contraction of atrial myocardium and ventricular myocardium
    2. functioning of the sinoatrial node and the atrioventricular node
    3. closing of the atrioventricular valves and the semilunar valves
    4. ejection of blood into the systemic circuit and the pulmonary circuit

  8. The cells that initiate the stimulus for contraction of heart muscle are normally located in the
    1. pulmonary trunk
    2. sinoatrial node
    3. right coronary artery
    4. central nervous system
    5. right atrioventricular valve

  9. Which heart chambers are dependent on the atrioventricular node, atrioventricular bundle and bundle branches in order to maintain normal rhythm?
    1. both atria
    2. right ventricle
    3. left ventricle
    4. both ventricles
    5. all four heart chambers
