Detailed dissection of heart
Interior of right and left ventricles, anterior view
Two incisions have been made in this specimen. The initial cut through the anterior wall of the heart has opened the right ventricle and conus arteriosus and has produced a large flap (3) which is retracted. The second cut (10) has been made through the interventricular septum and has been extended upwards to include the anterior wall of the aorta. The septum has been retracted to expose the interior of the left ventricle (17).
