Across
- 5. Takes blood away from the left ventricle to the rest of the body
- 7. conduction fibers that conduct impulses through the ventricles of the heart
- 8. Separates it into a right half from the left
- 12. the left ventricle does not close properly
- 14. sends out an electrical impulse that begins and regulates the heart rate
- 15. dense network of fibers of conduction at the junction of the superior vena cava and right atrium
- 16. The inner lining is smooth tissue
- 17. This bundle divides into a right and left branch
- 18. A large venous channel located on the posterior wall of the heart
- 19. Takes blood away from the right ventricle
- 20. When blood flow to heart is blocked or stop beating
- 22. The left chamber of the heart
- 23. made up of three half-moon-shaped cups, located between the junction of the aorta and the left ventricle of the heart
Down
- 1. atrioventricular valve between the left atrium and left ventricle; allows blood to flow from left atrium to left ventricle
- 2. a test done to evaluate the right and left ventricles.
- 3. One of the lower chambers of the heart
- 4. conducting fibers in the septum; also known as the bundle of His
- 6. heart valve at the opening of the pulmonary artery that allows blood to flow from the right ventricle into the pulmonary artery
- 9. the large venous blood vessels that bring deoxygenated blood
- 10. Makes up major portion of the heart
- 11. A double layer of serous and fibrous tissue
- 13. small mass of interwoven conducting tissue located between the atria and ventricles
- 21. valve between right atrium and right ventricle
