  2. 6. The sequence of events taking place during one heart beat.
  3. 9. The main artery of the body.
  4. 10. Blood vessels that carry blood to the heart from other parts of the body.
  5. 12. Red pigment found in red blood cells that reversibly binds to oxygen.
  6. 13. The muscle tissue that makes up most of the heart.
  7. 14. Valve with two flaps that lies between the left atrium and the left ventricle.
  8. 15. Circulation from the heart to the rest of the body and then back to the heart.
  9. 16. Blood vessels that carry blood away from the heart.

Down
  1. 1. Large veins that carry deoxygenated blood to the heart.
  2. 2. Maintaining a relatively constant environment for the cells within the body.
  3. 3. Valve with three flaps that lies between the right atrium and the right ventricle.
  4. 4. The smallest type of blood vessel whose function is to facilitate the exchange of substances between blood and tissues.
  5. 5. Originating in muscle tissue rather than nerve impulses.
  6. 7. A patch of muscle in the wall of the right atrium whose rate of contraction is faster than the rest of the cardiac muscle and initiates the contraction of the heart.
  7. 8. Circulation from the heart to the lungs and back.
  8. 11. An almost colorless fluid present in lymph vessels; similar in composition to blood plasma.
  9. 14. Red liquid that circulates in the arteries and veins carrying oxygen to and carbon dioxide away from the tissues of the body.
  10. 15. A partition separating the two chambers of the heart.
