This medical exhibit shows the anterior view of the lungs and upper abdomen at rest and during inhalation to demonstrate normal breathing. During inhalation, the diaphragm drops down, displacing the liver and spleen in order to allow the lungs to expand. Anatomy highlighted in this view includes the nasal cavity, oral cavity, trachea, esophagus, lungs, heart, diaphragm, spleen, liver, and the stomach.
