        Right Subclavian A.
        
        Right common carotid A.
      - Left common carotid A.
      - Left Subclavian A.
    - - Common carotid A and Internal jugular vein
      - Recurrent laryngeal nerve
- - - - Left superior pulmonary vein
      - Left inferior pulmonary vein
      - Pectinate muscles present
    - - Left AV valve - mitral/bicuspid valve
      - Aortic valve (left semilunar valve)
        
        Blood pools here and moves to Coronary artery
        
        Superiorly forms the aortic sinus --> then blood goes to Coronary artery
      - Aorta
      - Papillary muscles pull on chordae tendinae, to close AV valve
      - Trabeculae carneae - thick muscular wall with distinct ridges present
    - - Superior Vena Cava
      - Inferior Vena Cava
      - Coronary sinus opening - where blood drains from coronary sinus back into the heart
      - Pectinate muscles present (ridged muscle wall) only present in the atria
      - Fossa ovalis - was the foramen ovalis before birth, wall between left and right atrium
      - Crista terminalis - ridge that separates pectinate muscles from the smooth wall
    - - Right AV valve - tricuspid valve
      - Papillary muscles present, pull on chordae tendinae to close AV valve
      - Pulmonary trunk
      - Pulmonary valve (right semilunar valve)
      - Trabeculae carneae present
