  2. the A-V valves are
    mitral and tricuspid valves
  3. the inner sac covering and enclosing the heart is the
    visceral pericardium
  4. the skeleton of the heart consists of
    fibrous rings encircling the atrioventricular orifices, the aortic, pulmonary proximal ends and the interventricular septum
  5. which of the following represents the correct sequence of parts throught which blood moves in passing from the vena cava to the lungs?
    right atrium, tricuspid valve, right ventricle, pulmonary valve
  6. The correct sequence of parts that function to carry cardiac impulses is
    S-A node, A-V node, A-V bundle, Purkinje fibers
  7. In an ECG pattern the T-wave is caused by
    repolarization of ventricular muscle fibers
  8. Diagnosis of hypertension is indicated by
    diastolic pressure of 91 mmHg or more
