the posterior intercostal arteries arise from which artery?
a keel-shaped cartilage lying at the tracheal bifurcation--it separates the right main stem bronchus from the left main stem bronchus.

entry of air into the pleural cavity resulting from penetrating wound to parietal pleura
midline incision through the sternum
Because of its angle with the trachea and size of the main bronchus, a bronchoscope would pass more readily into which lung?
occurs if a sufficient amount of air enters the pleural cavity causing the tension adhering visceral to parietal pleura to break
anterior rami of T1-T11 form which nerves
the visceral and parietal plurae are continuous at the ...?
accumulation of a significant amount of fluid in pleural cavity
indents the anterioinferior aspect of the left lung
ligament that is a continuity between the pleural and parietal cavities that extends between parietal and mediastinum
