Answer:
Coronary sulcus travels between the atria and the ventricles.
Explanation:
Coronary sulcus surrounds most of the heart and limits two sectors: The atrial and ventricular sectors. The atria are located occupying a posterior superior position and the anteroinferior ventricles. This cardiac cone has a groove parallel to the base that is established by dividing it into an upper portion (the atria) and a lower portion (the ventricles). It is called ''coronary groove'' because it is arranged as a crown around the heart cone.
