Question

De Auricles and ventricles contract together . Yes or No
​

Answer 1

Explanation:

During systole, the auricles contract before the ventricles. The blood from the auricles reach the ventricles during contraction. After this, the ventricles contract. The blood from the right ventricle moves into the pulmonary artery to reach the lungs.

Answer 2

Answer:

yes

Explanation:

The contraction phase or systolic phase begins when the auricles contract. The blood forces its way through the mitral and tricuspid valves into the ventricles. The ventricles contract and force the blood through the semi-lunar valves, that is, the pulmonary and aortic valves.
