  1. when the ventricular walls relax
    the bicuspid and tricuspid valves open
  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
  9. The pulmonary circuit
    sends deoxygenated blood to the lung
  10. which of the following supplies blood to parts of the intestinal tract?
    superior mesenteric artery
  11. which of the following is not a branch of the aorta?
    pulmonary artery
  12. The phrenic artery provides blood to the
    diaphragm
  13. which type of blood vessel holds the greatest volume of blood?
    veins
  14. Certain ions in the blood will influence heart action; _ ions may suddenly stop the heart, causing cardiac arrest
    excessive of potassium (k+)
  15. plasma protiens that remain in the blood capillaries help to
    maintain the osmotic pressure of the blood
  16. with a stethoscope placed on the 5th right intercostal space, sounds can be heard coming from the
    tricuspid valve
  17. All of the following are important for returning blood to the heart except:
    the hydrostatic blood in the arterial side
  18. In an ECG pattern the P wave is caused by
    depolarization of atrial muscle fibers
  19. with a stethoscope placed on the 2nd left intercostal ace, sounds can be heard coming from the
    pulmonary semilunar valve
  20. The semilunar valves are
    aortic and the pulmonary valves
  21. Arterial blood pressure depends on a variety of factors; increase in the blood pressure could be due to:
    Increase in the blood volume and heart rate
  22. The normal pacemaker of the heart is the
    sinoatrial node (SAN)
  23. The right atrium receives blood directly from the
    superior vena cava, inferior vena cava, and coronary sinus only
  24. The blood pressure in the systemic arteries is greatest during
    ventricular systole
  25. When a persons' pulse is taken by palpation near the thumb on
    radial artery
