Across
- 3. Is responsible for transporting blood to the heart there are four main arteries
- 6. the largest artery of the body and carries blood from the heart to the circulatory system
- 10. Returns deoxygenated blood from the body and moves it to the right atrium
- 12. Left ventricular contraction forces oxygenated blood through the aortic valve to be distributed to the entire body.
- 13. The right ventricle pumps blood low in oxygen to the lungs. In the lungs, the blood then gets a "refill" of oxygen.
Down
- 1. cardiac muscle cells that conduct electrical impulses that allow coordinated contraction of cardiac muscle
- 2. generates an electrical signal that causes the upper heart chambers (atria) to contract
- 4. Isone of the four main chambers of the heart stores and transports deoxygenated blood
- 5. a sequence of alternating contraction and relaxation of the atria and ventricles in order to pump blood throughout the body.
- 7. receives oxygen-rich blood from the lungs and pumps it to the left ventricle
- 8. separates the ventricles and allows for proper blood flow through the heart
- 9. a protective, fluid-filled sac that surrounds your heart and helps it function properly.
- 11. connect the electrical systems of the atria and the ventricles, providing electrical impedance from the atria and an intrinsic pacemaker in its absence
