  • cardiovascular system
    • superficial anatomy of the heart
      • atria
        • thin walled
        • upper chambers
      • ventricles
        • thick, muscular
        • lower chambers
      • apex points down and tips slightly to the left
    • internal anatomy of the heart
      • atriums
        • right and left
        • separated by the interatrial septum
      • ventricles
        • right and left
        • separated by the interventricular septum
    • structure of the heart wall
      • 3 layers
      • epicardium
      • myocardium- thickest layer, cardiac muscle
      • endocardium
    • valves of the heart
      • atrioventricular (AV) valves
        • separates the atria from the ventricles
        • tricuspid- right
        • bicuspid- left
      • semilunar valves
        • separate the ventricles from the great vessels
        • pulmonary semilunar valve
        • aortic semilunar valve
