Across
- 3. The heart valve that has three cusps
- 4. The aortic and pulmonary valve are both ____________ valves
- 5. Part of the cardiac cycle when contraction of a chamber of the heart that drive blood out of that chamber, pressure in ventricle exceeds pressure in atria
- 10. Fibrous cords that tether the cusps to the interior of the ventricular wall, help prevent back flow of blood
- 14. Part of the wall of the heart, made up of cardiac muscles with the left ventricle being the thickest
Down
- 1. These blood vessels carry blood away from the heart
- 2. This node is located at the top of the atrioventricular septum, serve as auxiliary pacemakers, protect ventricles from beating too fast
- 6. Part of the wall of the heart, continuous with the endothelial lining of blood vessels
- 7. These fibers carry action potentials into ventricular myocardium
- 8. This node is located in the right atrium, known as the pacemaker of the heart
- 9. These blood vessels carry blood to the heart
- 11. Part of the wall of the heart, has a serous inner layer of pericardium
- 12. Part of the cardiac cycle when relaxation of a chamber of the heart just prior to and during the filling of that chamber
- 13. The heart valve that has two cusps, also known as the Mitral valve
