The azygos vein arches over it from behind; and the right pulmonary artery lies at first below and then in front of it.
About 2 cm. from its commencement it gives off a branch to the upper lobe of the right lung.
This is termed the eparterial branch of the bronchus, because it arises above the right pulmonary artery.
The bronchus now passes below the artery, and is known as the hyparterial branch; it divides into two branches for the middle and lower lobes.
If a foreign body in the airway passes through the trachea, it will most likely enter the right main bronchus instead of the left, due to the straighter alignment of the right bronchus to the trachea.
