Question

What happens during the isovolumic phase of the ventricular systole?

Answer 1

Isovolumetric Contraction:

1. During the period of isovolumetric contraction, the ventricles contract.
2. The aortic and pulmonary valves get closed as the ventricles lack sufficient force to open them.
3. These atrioventricular valves are closed when the period of isovolumetric contraction occurs.
4. The period of isovolumetric contraction is for a very short duration.
5. The volume of the ventricular blood remains unchanged since all four valves are closed.
