The aortic root is located to the right of the right auricle and the superior vena cave and the the left of the pulmonary artery. The aortic root is enclosed within the pericardium, which is a protective sac containing the heart and major arteries. The ascending aorta transports blood upward from the left ventricle of the heart.
