11. Three margins

12. Four grooves Interatrial groove coronary sulcus posterior interventricular groove anterior interventricular groove cardiac apical incisure

13. The chambers

15. The right atrium atrium proper sinus venarum cavarum sulcus terminalis

16. Four orifices orifice of superior vena cava orifice of coronary sinus atrioventricular orifice orifice of inferior vena cava Valve of inferior vena cava

17. Atrioventricular orifice

18. The interatrial septum fossa ovalis

19. The interior of the right atrium crista terminalis pectinate muscle

23. The interior of the right ventricle Tricuspid complex Conus arteriosus Supraventricular crest Tricuspid valve Chordae tendineae Trabeculae carneae Papillary muscles

24. Septomarginal trabecula

25. The right atrioventricular orifice and valve The orifice and valve of the pulmonary artery

26. The left atrium Left auricle Opening of the pulmonary vein Left atrioventricular orifice

27. The left ventricle The interior of the right ventricle Mitral complex Mitral valve Chordae tendineae Trabeculae carneae Papillary muscle
