Lungs Aspiration Pneumonia which lung part affected?

A 63-year-old male with a history of stroke and resultant severe oropharyngeal dysphagia develops a right lower lobe pneumonia after an episode of vomiting. This type of aspiration pneumonia commonly affects the right lower lung lobe because:

A. The right main bronchus is longer than the left main bronchus
B. The right main bronchus is straighter than the left main bronchus
C. The right main bronchus is narrower than the left main bronchus
D. The right lower lobe receives a richer blood supply than the left lower lobe
E. Vascular resistance is higher in the right lower lobe than the right upper lobe......

it's a uworld right?
i'd take B....if you think about it's the only one that makes sense...

we know that the infection is in the right lower lobe so:

A- the length of the way has nothing to do with 'where the vomit will go'...it just falls
C- if something is narrower it wouldn't go that way either if you have a nice big right bronchus to go
D- blood supply has nothing to do with 'where the vomit goes' neither does E

hopes to be right

Answer is B for any object entering the lungs.

Blood supply and Vasc Resistance would be things to look for when comparing apex vs base of lung. ex: Aerobic Tuburc

Default It's B.

That's why bronchus obstruction likely takes place in right main bronchus, which is shorter and straighter.
