  1. 3. Deposits of fatty material that build up inside the blood vessels.
  2. 6. Veins that carry oxygenated blood from the lungs to the heart. TWO WORDS NO SPACES
  3. 7. The large vein that collects blood from the lower parts of the body. THREE WORDS NO SPACES
  4. 9. The largest artery in the body. It carries oxygenated blood away from the heart to arteries serving the body.
  5. 10. The then, smooth tissue that lines the inside walls of the heart.
  6. 12. The only arteries that carry deoxygenated blood. They carry blood from the right ventricle to the lungs. TWO WORDS NO SPACES
  7. 13. The heart muscle. It's the thickest layer of the heart.
  8. 15. "Doors" that open and close and are located between each atrium and ventricle and between each ventricle and the blood vessel leaving that ventricle.
  9. 16. Two of the four valves found in the heart. THese half-moon shaped valves keep the blood from flowing backwards into the ventricles from the aorta and pulmonary artery when the heart relaxes between beats. TWO WORDS NO SPACES
  10. 19. A special fibrous sac that holds the heart in place.
  11. 20. The thick, muscular wall between the two ventri
Down
  1. 1. The momentary stretching of arteries caused by the rush of blood forced out of the heart with each beat (contraction)
  2. 2. An unique cluster of cells inside the heart that causes the heart to beat on its own.
  3. 4. Two of the four valves found in the heart. THese valves are placed between the atrium and ventricle on each side. TWO WORDS NO SPACES
  4. 5. The first number in a person's blood pressure. It indicates the pressure against the arterial walls when the ventricles contract. THREE WORDS NO SPACES
  5. 8. The second number in a person's blood pressure. It indicates the pressure against the arterial walls when the ventricles relax. THREE WORDS NO SPACES
  6. 11. A measurement of the force of the blood pushing against the walls of the arteries. TWO WORDS NO SPACES
  7. 14. The large vein that collects blood from the upper parts of the body. THREE WORDS NO SPACES
  8. 17. The two lower chambers of the heart. THese muscular chambers push the blood out of your heart.
  9. 18. The thin wall between the two atria. TWO WORDS NO SPACES
  10. 21. The top two chambers of the heart
