Question: 1 / 400

What occurs during systole in the heart?

Aortic and pulmonary valves close and ventricles relax

Aortic and pulmonary valves open as ventricles contract

During systole, the phase of the heartbeat when the heart muscle contracts, the aortic and pulmonary valves open. This occurs as the ventricles contract forcefully, allowing blood to be ejected from the heart into the aorta and pulmonary artery. The contraction of the ventricles is crucial for pumping oxygenated blood to the body and deoxygenated blood to the lungs for oxygenation.

During this phase, the closing of the mitral and tricuspid valves prevents backflow into the atria and supports the forward motion of blood. Understanding the role of the aortic and pulmonary valves during this period is essential, as they directly influence the efficiency of blood circulation during the contraction phase of the cardiac cycle. This provides a foundation for grasping the dynamics of blood flow and pressure changes in the circulatory system.
