question

When the atria contract, only 30% of the ventricular space becomes filled. How does the additional 70% become filled? Describe the process of the cardiac cycle in general.

category

biology

options

  1. Ventricular filling is achieved through nervous stimulation.
  2. 70% of the ventricular filling occurs during diastole due to passive flow as the atrial pressure is greater than the ventricular pressure.
  3. The additional 70% is filled by the gravitational force when the body is in a specific position.
  4. The remaining ventricular space is filled by pulmonary backflow during inhalation.
  5. Ventricular filling is supplemented by the contraction of auxiliary heart chambers.
  6. Ventricular filling is completed by muscular constriction of the ventricles.
  7. Ventricular filling for the remaining 70% is regulated by hormonal changes during the cardiac cycle.
  8. Ventricular filling occurs during systole due to active flow.
  9. The remaining 70% of ventricular filling is due to contraction of the atria.
  10. The last 70% of ventricular filling is aided by the opening and closing of the semilunar valves.
