3 15. What is between the parietal and visceral serous pericardial layers: a. fibrous pericardium b. an air filled space c. serous fluid d. cardiac skeleton e. nothing, since they are not even close to each other 16. Blood in the right ventricle would be in contact with which heart wall layer: a. endocardium b. superficial myocardium c. deep myocardium d. epicardium e. parietal pericardium 17. The function of papillary muscles is: a. essential part of the ventricular conducting system b. anchorage of and pull on chordae tendineae c. stenosis d. control of blood turbulence e. control of semilunar valves 18. Which heart chamber is the most powerful: a. right ventricle b. left ventricle c. right atrium d. left atrium e. none of the above, since they are all equal 19. The equivalent of the chest or abdominal wall is: a. fibrous parietal pericardium b. serous parietal pericardium c. visceral pericardium d. endocardium e. myocardium 20. Which of the following is not related to the right side of the heart: a. sino-atrial node b. pulmonary semilunar valve c. bicuspid valve d. venae cavae e. atrio-ventricular node 21. Which of the following is not related to the left side of the heart: a. sino-atrial node b. pulmonary semilunar valve c. tricuspid valve d. atrio-ventricular node are on the right side

4 22. The atrio-ventricular valves are closed: a. while the ventricles are in diastole b. when the ventricles are in systole c. by the movement of blood from atria into ventricles d. while the atria are in systole e. at all times 23. The semilunar valves open when: a. arterial pressure is lower than the ventricular pressure b. the ventricles are in diastole c. the atria are in systole d. blood within the aorta and pulmonary trunk pass into the ventricles e. the ventricles are in systole 24. The wall of the left ventricles receives blood from: a. anterior descending artery b. circumflex artery c. posterior descending artery d. all of the above e. none of the above 25. Semilunar valves close due to: a. chordae tendineae pulling them downwards while blood is forced against them from underneath b. a vacuum within the aorta and pulmonary artery c. the depolarization of the sino-atrial node d. blood catching in them and blocking the opening back into the ventricles e. none of the above 26. Atrio-ventricular valves close due to: a. a vacuum within the aorta and pulmonary trunk b. the depolarization of the sino-atrial node c. blood catching in them and blocking the opening, during ventricular diastole d. chordae tendineae pulling them downwards while blood is forced against them from underneath e. contraction of the fibrous parietal pericardium 27.

What keeps the atrio-ventricular valves closed during ventricular systole: a. counteracting effects from downward pulling by the papillary muscles on the chordae tendineae and by blood pushing against the underside b. counteracting effects from atrial systolic downward pushing while the chordae tendineae push from the underside c. blood catching in the underside of the three pouch-like flaps, thus preventing eversion back up into the atria d. stenosis of the foramen ovale

5 29. Which valve controls the opening between the left atrium and left ventricle: a. bicuspid b. tricuspid c. aortic semilunar d. pulmonary semilunar e. foramen ovale 30.
