Across
  1. 7. CIRCULATION the part of systemic circulation that provides the heart muscle with oxygen and nutrients and carries away waste products
  2. 8. a portion of a thrombus that breaks off and moves through the bloodstream.
  3. 10. the constriction of the muscular wall of an artery to increase blood pressure.
  4. 11. the widening of the muscular wall of an artery to decrease blood pressure
  5. 15. the middle and thickest layer of the heart. It is made primarily of cardiac muscle.
  6. 16. a membrane that covers the heart and large blood vessels attached to it.
  7. 18. the outermost layer of the wall of the heart.
  8. 20. PRESSURE the blood pressure measured when the left ventricle of the heart contracts.
Down
  1. 1. NODE a small bundle of heart muscle tissue in the superior wall of the right atrium that sets the rhythm of the heart’s contractions.
  2. 2. OF HIS this is the node located between the ventricles of the heart that carries the electricl impulse from the AV node to the bundle branches.
  3. 3. NODE node that is located between the atria of the heart. After the electrical impulse reaches the atrioventricular node, the atria contract and the impulse is sent to the ventricles.
  4. 4. thickness
  5. 5. CIRCULATION the circulation of blood through the arteries, capilaries and veins of the general system, from the left ventricle to the right atrium.
  6. 6. the innermost layer of the heart.
  7. 9. an abnormal narrowing of a body passage
  8. 12. TENDINEAE cord-like structures that attach the cusps of the heart valves to the papillary muscles in the ventricles.
  9. 13. PORTAL SYSTEM the collection of veins carrying blood to the liver.
  10. 14. OUTPUT the product of heart rate and stroke volume, measured in liters per minute; the amount of blood that is pumped by the heart in 1 minute.
  11. 16. FIBERS cardiac fibers that are located in the lateral walls of the ventricles.
  12. 17. CIRCULATION the passage of blood from the right ventricle through the pulmonary artery to the lungs and back through the pulmonary veins to the left atrium.
  13. 19. PRESSURE the blood pressure measured when the heart relaxes.
