Define a recess.
Recesses are spaces between the visceral and costal pleura.
Describe the location of the costomedial recess.
Describe the surface markings of the lungs.
Describe the borders of the lungs.
Describe the functional role of the lung Hila
Areas of the central mediastinal surfaces where the structures of the lung roots enter. The order of structures surrounding and within each helium mirrors the respective root, except that it is slightly more lateral.
Describe the contents of the Hila
Describe the structures and differences between the right and left Hila.
Pulmonary artery is anterior to bronchus in right hilum but superior to it in left hilum.
Identify the aorta on a CT scan.
Identify the contents of the superior mediastinum.
- Aortic arch and its branches

- Trachea
- Oesophagus
- Thoracic duct
- Vagus and phrenic nerves

Identify the ascending, descending aorta, superior vena cava and pulmonary artieries in the CT scan.
Identify the ascending aorta, descending aorta and superior vena cava in the CT scan with contrast.
Identify the aortic arch and superior vena cava on the axial CT.
