- The dorsal surface of the heart lies near the bodies of the vertebrae and its anterior surface sits deep to the sternum and costal cartilages. The great veins, the superior and inferior venae cavae, and the great arteries, the aorta and pulmonary trunk, are attached to the superior surface of the heart, called the base.
The base of the heart is where the great vessels are attached. The inferior, pointed tip of the heart. A deep groove, marking the border between the atria and the ventricles. Shallow depressions that mark the boundary between the left and right ventricles.
The base is the posterior aspect of the heart. It is formed largely by left atrium and a narrow portion of the right atrium.
