Sheep Heart
Anterior longitudinal sulcus
Left Auricle Anterior longitudinal sulcus You can find the anterior side of the heart by finding the auricle that you can see completely; it is the left auricle. The anterior longitudinal sulcus is on that side and the coronary sinus is on the posterior side.
