Across
  1. 6. The ability to the heart to contract
  2. 7. The rate at which deoxygenated blood returns back to the heart
  3. 10. Can effect venous return when a person is standing
  4. 11. The amount of times your heart beats in a minute
  5. 12. Sum of factors which effect end - diastolic volume and fibre length of ventricles
  6. 13. X's law which describes the relationship between force of ventricle contraction and ventricle fibre length
Down
  1. 1. These are present during acidosis and are a negative inotrope
  2. 2. The pressure and length of these is what effects preload
  3. 3. Hormone which is a positive inotrope
  4. 4. Sum of factors which put pressure on ventricle walls. The load at which ventricles must pump against
  5. 5. Amount of blood pumped from the left ventricle every time your heart beats
  6. 6. The total amount of blood pumped from the heart
  7. 8. Pressure has to be lower in this vessel compared to the heart for blood to move out of the heart
  8. 9. Something that affects the force of contraction of the heart
