Across
  1. 4. Vena Cava Carries deoxygenated blood from the body.
  2. 6. Valve located between the right ventricle and the pulmonary artery.
  3. 8. Double-layered membrane surrounding the heart
  4. 10. Valve Controls the opening between the right atrium and the right ventricle. This valve has three leaflets/cusps.
  5. 13. Ventricle Receives deoxygenated blood from the right atrium and pumps the blood through the pulmonary artery
  6. 14. of His AV bundle in which the AP travels through to reach the ventricles
  7. 15. Atrium pumps blood from vena cava into right ventricle
  8. 17. Valve Heart valve between the left ventricle and the aorta.
  9. 18. Node Pacemaker of the heart.
Down
  1. 1. amount of chambers
  2. 2. The thick middle layer that develops the pressure required to pump blood through the vessels.
  3. 3. Branches electrical signal travels from AV bundle travel through these branches located in the interventricular septum
  4. 5. Inner layer of the heart lining the chambers to reduce friction and the blood passes through.
  5. 7. base of heart
  6. 9. Valve Heart valve between the left atrium and left ventricle
  7. 11. Fibers Arise from the bundle branches at the bottom of the heart.They branch extensively and deliver the AP to the contractile cells
  8. 12. Are part of the circulatory system
  9. 14. red liquid that carries oxygen and circulates throughout the body
  10. 16. Artery that carries blood directly from the heart to the rest of the body
  11. 17. Node .1 second delay from receiving AP till it transmits it to the ventricles.
