Across
- 3. Special connections between cardiomyocytes
- 6. The spiral arrangement of skeletal muscle in the heart that maximizes blood pumped in each heartbeat
- 9. Ventricle that is C shaped and has very THIN myocardium
- 11. The side of the heart receiving high oxygen blood
- 14. Increases the surface area of the connections between cells (feature of intercalated disks)
- 15. Contains adipose (fat) tissue that prevents compression of heart blood vessels
- 17. Organization of motor proteins in cardiac muscle tissues, creates striations
- 18. Protein based structures that create a water-filled connection between the cytoplasm of each myocyte
- 19. Means that the heart controls its own rhythmic contractions without input from the nervous system
Down
- 1. Chambers of the heart that receive blood
- 2. Protein-based structures that strongly bind the two cells on either side of the disk together
- 4. Condition where excess fluid around heart causes pressure to squeeze heart and prevents proper pumping
- 5. Valve located between left atrium and left ventricle
- 7. The complete cycle of pumping in a single heartbeat
- 8. Central space of the chest where the heart is located
- 10. Space filled with a thin film of fluid surrounding the heart
- 12. Entry point for the great vessels of the heart
- 13. Structures that ensure one way flow of blood through the heart
- 16. Circuit that carries low oxygen blood from to the heart, to the lungs, and back
