How many lobes does the right lung have?

Explanation:
Lungs are divided into lobes by deep grooves called fissures, and the right lung is split into three sections by two fissures. The oblique fissure runs diagonally, and a horizontal fissure cuts across the middle, creating the superior lobe at the top, a middle lobe in the middle, and an inferior lobe at the bottom. This arrangement gives the right lung three lobes. For contrast, the left lung has only two lobes because the heart occupies space on that side.
