MEDIASTINUM

This life size model is composed of 5 parts, including a 2-part heart that

provides an interior view of the chambers and valves. The sternum and thymus are removable to

reveal the pericardical sac and the major pulmonary and systematic vessels. The trachea and

esophagus are shown entering the mediastinum through the superior thoracic aperture; the

inferior thoracic aperture is delimitated from the diaphragm musculature.
