  • The human heart is four-chambered with a distinct transverse groove called atrioventricular groove or coronary sulcus that divides it into a smaller anterior atrial part and a posterior ventricular part 
  • The left and right atria are separated externally by a shallow vertical interatrial groove. 
  • Two grooves marking the boundary between right and left ventricles are anterior interventricular and posterior interventricular sulcus.
