General

Surface

Internal

Chambers

Right heart	* (venae cavae, coronary sinus) → right atrium (atrial appendage, fossa ovalis, limbus of fossa ovalis, crista terminalis, valve of inferior vena cava, valve of coronary sinus) → tricuspid valve → right ventricle (infundibulum, moderator band/septomarginal trabecula, crista supraventricularis), → pulmonary valve → (pulmonary artery and pulmonary circulation)
Left heart	* (pulmonary veins) → left atrium (atrial appendage) → mitral valve → left ventricle → aortic valve (aortic sinus) → (aorta and systemic circulation)

Layers

Endocardium	* heart valves
Myocardium	* Conduction system cardiac pacemaker SA node Bachmann's bundle AV node bundle of His bundle branches Purkinje fibers
Pericardial cavity	* pericardial sinus
Pericardium	* fibrous pericardium sternopericardial ligaments serous pericardium epicardium/visceral layer fold of left vena cava
