Answer:
When the ventricles contract, blood is pumped out of the heart.
Step-by-step explanation:
- When the ventricle of heart is filled with blood then it contracts allowing the blood to flow throughout the body.
- To prevent the return of blood during the ventricular systole, mitral valve is closed and aortic valve is opened.
- The opening of aortic valve passes the blood to aorta which is then distributed through out the body.
- When left ventricle contracts the right ventricle also contracts at the same time.
