Through the"Void"....

                                                       we start at the top of the chest...

                       

             on he left section of chest cavity (filled with "orbs"... Large one at top) nothing on right side

hit something that changed "type" of image...

                     A tour through the vast void in the right side of Stacey's chest cavity

These seem to be veins upon the outer membrane of these Orbs...

                              much further down chest... right side still a "void"....

                                                                (Valves of heart)

                   near lower heart ...(near remaining bit of lung) veins around lower edges of "Hole"...
