The ventricles of the heart are separated by two grooves, one of which, the anterior longitudinal sulcus (or anterior interventricular sulcus), is situated on the sternocostal surface of the heart, close to its left margin. The other groove separating the ventricles is the posterior longitudinal sulcus.

atria (interatrial septum, musculi pectinati) | ventricles (interventricular septum, trabeculae carneae, chordae tendinae, papillary muscle) | valves

base | apex | grooves (coronary/atrioventricular, interatrial, anterior interventricula, posterior interventricular) | surfaces (sternocostal, diaphragmatic) | borders (right, left)

right heart: (vena cavae, coronary sinus) → right atrium (auricle, fossa ovalis, limbus of fossa ovalis, crista terminalis, valve of the inferior vena cava, valve of the coronary sinus) → tricuspid valve → right ventricle (conus arteriosus, moderator band/septomarginal trabecula) → pulmonic valve → (pulmonary artery and pulmonary circulation)
