How many lobes does the left lung have?

Explanation:
Lung lobes are divided by fissures, and the left side has fewer space available because the heart sits in that side of the chest. The left lung is divided into two lobes—the upper and lower—by the oblique fissure, and it also has a cardiac notch where the heart sits. This contrasts with the right lung, which has three lobes (upper, middle, and lower) thanks to an additional horizontal fissure. So, the left lung has two lobes.
