How many lobes does the left lung have?

Explanation:
Two lobes in the left lung are separated by a single oblique fissure, with a superior lobe above and an inferior lobe below. The heart sits on the left side, creating a cardiac notch and leaving space for only two lobes on that side. The right lung, in contrast, has three lobes because it has both an oblique fissure and a horizontal fissure, which create a middle lobe. So the left lung has two lobes: superior and inferior.
