Apex of the heart Cusp of tricuspid valve Right atrium Chord

Apex of the heart Cusp of tricuspid valve Right atrium Chordae tendineae Aortic semilunar valve Trabeculae carneae Papillary muscle Interventricular septum Pectinate muscles Cusp of bicuspid valve Ascending aorta Left atrium

Solution

26 is left atrium

27 ascending aorta

28 tricuspid valve atrioventricular valve

29. Inter ventricular septum

30. Right atrium

31. Aortic semilunar valve

32. Bicuspid valve

33. Chordae tendinae

34.papillary muscles

35. Apex

So these are the parts of heart visible when cut open. Hope this helps..
