During ventricular systole, the left ventricle contracts and its pressure rises above the pressure in the aorta. This pressure difference opens the aortic semilunar valve, allowing blood to be ejected into the aorta for the systemic circulation. The mitral valve (between left atrium and left ventricle) and the tricuspid valve (between right atrium and right ventricle) are closed during this phase to prevent backflow into the atria, and the pulmonary valve (between the right ventricle and pulmonary artery) handles the right heart, not the left.
