Which right lung lobe is the smallest?

Explanation:
The right lung’s lobes differ in size, and the middle lobe is the smallest. It lies between the horizontal fissure (separating it from the superior lobe) and the oblique fissure (separating it from the inferior lobe). The middle lobe contains only two bronchopulmonary segments (lateral and medial), whereas the superior lobe has more and the inferior lobe has the most, so its overall volume is smaller. There isn’t a normal “accessory” lobe in the right lung, which is why that option isn’t correct.
