The function is to transport air to the rest of the body.
A primary bronchus is the first branch off the trachea, further branching leads to the secondary bronchus and then tertiary as you get deeper into the lung.
The primary bronchus that is the more likely site for an inspired object to become lodged is the right bronchus. It has a straighter alignment compared to the left bronchus.

The trachea branches off into the primary bronchus , secondary bronchus etc all the way to the alveoli.The primary bronchus is the first extension of the trachea to enter the lungs.
The function of the left and right primary bronchi is to allow the passage of air to and from the lungs and trachea/windpipe. The only difference between the two bronchi is that the angle of the right bronchus at the carina (point of bifurcation) is straight while the left one is more angled. This is why in case someone aspirates something, it is almost always found lodged in the right bronchus instead of the left (despite sharing a common passageway/trachea).
The right primary bronchus is larger in diameter.
An obstruction in the right primary bronchus will affect oxygen intake. The right lung will not have the ability to draw in as much oxygen as the left lung, resulting in oxygen dissociation.
The right primary bronchus is more likely to have an inspired object become lodged in itself because it is more wide than the left primary bronchus and is also located at a steeper angle. It is more wide because the right lung is larger and needs a wider bronchus for air to fill it up.
