  1. 4. blood vessel that carries blood away from the heart (A)
  2. 6. blood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle (CA)
  3. 9. divides the right and left sides of the heart (S)
  4. 10. the electrical impulse that initiates a chain reaction resulting in a muscle contraction (D)
  5. 11. valve also known as the bicuspid valve; located between the left atrium and left ventricle (MV)
  6. 13. relaxation of the ventricles represents the lowest blood pressure measured (D)
  7. 15. ventricular contraction generates the highest blood pressure measured (S)
  8. 16. each of the two lower chambers of the heart that pumps blood out of the heart (V)
  9. 17. upper chamber of the heart that receives blood (A)
  10. 18. microscopic blood vessels where substances are exchanged between the blood and the body cells (C)
Down
  1. 1. extend from branches of AV bundle, stimulate muscle fibers in the ventricular walls (PF)
  2. 2. valve between the right atrium and the right ventricle (TV)
  3. 3. elevated blood pressure (H)
  4. 5. the pressure that is exerted by the blood against the walls of blood vessels (BP)
  5. 7. carries blood to the lungs for gas exchange and returns it to the heart (PC)
  6. 8. the graphic record/representation of the heart's electrical activity (ECG)
  7. 12. thickening, loss of elasticity, and hardening of arterial walls (A)
  8. 14. the node that serves as the heart's pacemaker, located in the wall of the right atrium (S)
