Has an apex (projects above the clavicle but not above the neck of the first rib)
Has a base (rests on diaphragm)
Lungs: Costal Surface Separation Characteristics
Separated Anteriorly from Mediastinal Surface by Anterior Margine
Separated Inferiorly from the diaphragmatic surface by the inferior margin
Lungs: Hilus
Only location where it is not free of the pleural cavities
Contains the root of each lung and the pulmonary ligament
