Across
  1. 3. x-ray imaging of arteries after injection of contrast via a catheter into the aorta or an artery
  2. 5. Local widening of an arterial wall
  3. 7. High Blood pressure
  4. 8. Valve that separates the Left atria from the left ventricle
  5. 10. arm
  6. 12. Smooth layer of endothelial cells that lines the interior of the heart and heart valves
  7. 14. Decreased blood flow
  8. 17. Beat of the heart as felt through the walls of arteries
  9. 18. Valve that separates the Right atrium from the Left ventricle and form a one-way passage designed to keep the blood flowing in only one direction
  10. 19. heart
  11. 20. vein
Down
  1. 1. Echoes generated by high-frequency sound waves produce images of the heart
  2. 2. Inflammation of the membrane (pericardium) surrounding the heart
  3. 4. Large blood vessels that carry blood away from the heart; lined with connective tissue, muscle tissue, and elastic fibers with an innermost layer of epithelial cells (endothelium)
  4. 6. Measures blood pressure or the force that the blood exerts on the arterial walls
  5. 9. Walls that are only one endothelial cell in thickness; carry nutrient-rich oxygenated blood from the arteries and arterioles to the body cells; allow passage of O2 and nutrients out of the bloodstream and into cells; allows CO2 to get back to venules
  6. 11. X-ray imaging of blood vessels after injection of contrast material
  7. 13. Thinner than arteries; conduct blood (that has given up most of its O2) toward the heart from the tissues
  8. 15. Abnormal heart rhythms (dysrhythmias)
  9. 16. yellowish plaque, fatty substance
