Heart and lungs removed

heart and lungs removedHere the heart and lungs have been removed from the thoracic cavity.

The right atrium and left atrium are now more visible.  You can also see the pulmonary trunk leaving the right ventricle.  It is the white colored tube running between the right and left atria.

 

The trachea ("windpipe") that leads to the bronchi and the two lungs is visible at the top of the image as a large diameter tube.
