Across
- 2. the volume of blood pumped by the heart per minute
- 3. valve narrowing that increases afterload
- 7. loss of blood volume reducing preload
- 8. the amount of blood ejected by one ventricle per beat
- 11. nervous system division increasing heart rate and contractility
- 12. the 'load' against which the heart contracts in systole
Down
- 1. the law that states ventricular filling/preload is proportional to stroke volume
- 4. the number of heart beats per minute
- 5. ion essential for cardiac muscle contraction
- 6. the intrinsic force of heart contraction
- 9. the flow of blood returning to the heart
- 10. the resting stretch of cardiomycoytes, related to ventricular filling
