What blood vessel begins at the aortic valve of the left ventricle?

Blood is ejected from the left ventricle through the aortic valve into the first segment of the aorta—the ascending aorta. This portion begins exactly at the aortic valve and then continues upward before curving into the aortic arch and finally becoming the descending aorta. The pulmonary trunk comes from the right ventricle as part of the pulmonary circulation, not the systemic, so it doesn’t begin at the aortic valve. The ascending aorta is the vessel that starts right at that valve.
