heart

1. blood supply

   • superior/inferior vena cava
     • right atrium
       • right ventricle
         • pulmonary trunk/arteries
           • lung
             • 4 pulmonary veins
               • left atrium
                 • left ventricle
                   • ascending aorta
                   • left atrioventricular valve (mitral/bicuspid)
           • pulmonary trunk is anterior to the aorta
       • right atrioventricular valve (tricuspid)
       • base (upside pyramid)
       • coronary sinus
         • great cardiac vein
           • anterior interventricular artery [branch of LEFT coronary artery
         • middle cardiac vein
           • posterior interventricular artery [branch of RIGHT coronary artery]
         • small cardiac vein
           • marginal artery [branch of RIGHT coronary artery]
         • oblique vein of the left atrium
       • anterior cardiac vein
         • right ventricle
     • superior drains cervical region; inferior: drains lumbrosacral region
       • azygous venous system: drains thoracic region
     • right brachiocephalic vein
     • left brachiocephalic vein
       • left internal jugular v
       • left subclavian v

2. mediatinum

   • inferior mediastinum: anterior, middle, posterior, diaphragm
   • superior to T4: superior mediastinum
   • T4 (sternal angle)

3. visceral layer = epicardium

   • serous fluid
     • parietal layer
       • fibrous pericardium
       • serous pericardium
