How many valves are there between the right and left atrium?

c ( There are no valves between the right atrium and both the superior and inferior vena cava. In addition, there are no valves between the pulmonary veins and the left atrium.) Which of the following structures of the heart are not separated by valves?

Which chambers contract at the same time?

The contraction and relaxation of all four chambers happens at the same time. B. The right atrium and ventricle contracts at the same time and as they are relaxing the left atrium and left ventricle begin to contract.

Do the atria and ventricles contract at the same time?
