  1. Review Circulatory System , Heart & Blood

  2. What is the function of the chordae tendineae?

  3. Parasympathetic stimulation to the heart results in …..

  4. Which part of the brain regulates impulses to the heart?

  5. Which cranial nerve sends impulses to the SA node?

  6. Cutting the Vagus nerve causes?

  7. Blood from the systemic circulation is returned to the right atrium by the …..?

  8. Blood plasma consists out of… ?

  9. Formed elements of the blood consists ?

  10. Name the 5 WBCs ? Never Let Monkeys Eat Bananas !!!

  11. Atrioventricular valves prevent backflow of blood into the _____________; Semilunar valves prevent backflow into the ___________. • Atria; Ventricles • Lungs; systemic circulation • Ventricles, Atria • Capillaries, Lungs

  12. When the pressure in the L. ventricle becomes greater than the pressure in the aorta, the…. • Pulmonary semilunar valve is forced open • Aorta semilunar valve closes • Pulmonary semilunar valve closes • Aorta semilunar valve is forced open

  13. The correct sequential path of an action potential in the heart is ? • SA node – AV bundle – AV node – Purkinje fibers • AV node – SA node – AV node – AV bundle • SA node – AV node – AV bundle – Purkinje fibers • SA node – AV node – Purkinje fibers – AV bundle

  14. Blood from the coronary circulation is returned to the right atrium of the heart via … • the great cardiac arteries • the circumflex branches • the coronary sinus • the interventricular braches

  15. The visceral pericardium, or epicardium, covers the… • inner surface of the heart • outer surface of the heart • vessels in the myocardium • all of the above

  16. The great cardiac vein drains blood into the coronary sinus, which drain blood into the … • right atrium • left ventricle • left atrium • right ventricle

  17. The right side, serves as the ________ pathway pump, while the left side serves as the ________ pump. • systemic; pulmonary • pulmonary; hepatic portal • hepatic portal, cardiac • pulmonary; systemic

  18. Platelets are unique formed elements of the blood, because they … • initiate the immune response and destroy bacteria • are cell fragments and initiate blood clotting • can reproduce because they contain a nucleus • are only present during an allergic reaction

  19. Rh- (negative) blood indicates the… • presence of RH agglutinogen • presence of agglutinogen A • absence of the Rh agglutinogen • absence of agglutinogen B

  20. If Agglutinogen B meets with Agglutinin Anti –A, the result would be … • a cross – reaction • no agglutination would occur • the patient would be comatose • the patient would die.
