occurs if a sufficient amount of air enters the pleural cavity causing the tension adhering visceral to parietal pleura to break
main vein of the heart
union of subclavian & internal jugular veins create which vein?
inflammation of the pericardium

This collection of autonomic fibers is located at the base of the heart behind and within the concavity of the arch of the aorta.
midline incision through the sternum
left and right brachiocephalic veins drain into?

the main arterial supply for the pericardium
injury to which nerve can cause paralysis of the diaphragm
muscles in the wall of the right atrium are known as?
QuestionAnswer
the thick muscle layer of the heart
this node lies in the interatrial septum
the endothelial lining of all of the chambers of the heart
Because of its angle with the trachea and size of the main bronchus, a bronchoscope would pass more readily into which lung?
interference with venous return of blood to the heart due to an extensive accumulation of fluid in the pericardium (pericardial effusion)
this pleura covers the lungs and is adherent to all its surfaces
right lung has how many lobes?
