The atrioventricular valves prevent the backflow of blood into the atria when the ventricles are contracting. The semilunar valves prevent backflow from the arteries into the ventricles.

Yes, the aortic semilunar valve opens when the left ventricle contracts during systole. This allows blood to be ejected from the left ventricle into the aorta to be circulated throughout the body.

What pathway does the blood flow when the ventricles undergo contraction?

When the ventricles contract, the right ventricle pushes blood up through the pulmonary semilunar valve into the pulmonary arteries via the pulmonary trunk, and the left ventricle pushes blood up through the aortic semilunar valve into the Aorta.
