Mediastinum anatomy. Artwork of a frontal view of the structures located in the chest area known as the mediastinum, which lies between the lungs below the sternum. These include the oesophagus (pale pink) that leads to the stomach (outlined at bottom) below the diaphragm (red line). The heart, which is located in the mediastinum, has been removed. Its major blood vessels are present, including the aorta (red, vertical) and vena cava (blue). Pulmonary veins and arteries (red and purple) lead to and from the lungs either side. The trachea (grey) branches to supply the lungs with air. The vagus nerve (yellow) is also shown.
