Membranes of the Thoracic Cavity
A transverse section of the thorax, showing the contents of the middle and the posterior mediastinum. The pleural and pericardial cavities are exaggerated since normally there is no space between parietal and visceral pleura and between pericardium and heart.
This transverse diagram of the thorax indicates the transverse thoracis, internal mammary vessels, left phrenic nerve, heart, rib, pleural cavity, pulmonary arteries, sympathetic trunk, thoracic duct, vagus nerves, azygos vein, pulmonary pleura, costal pleura, lungs, sternum, and thoracic aorta.
