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