How many lobes has the right lung?

Answer 1

The right lung has 3 lobes.

The left lung has 2 lobes.

The right lung is separated into 3 lobes by two fissures. The first is the horizontal fissure that divides it into the superior lobe and middle lobe. The second is the oblique fissure, which divides the middle lobe from the inferior lobe.

The left has only two lobes because, instead of a middle lobe, it has a cardiac notch for the heart to fit into. In the left lung, there is only the oblique fissure, which divides that lobe into the superior and inferior lobes. It also has what's called a lingula. "Lingua" is "tongue" in Latin and so the lingula (little tongue) is a tongue-like projection at the inferior part of the superior lobe.
