Which lung has three lobes?

The right lung has three lobes, which are the upper lobe, middle lobe, and lower lobe. This anatomical structure is essential for understanding respiratory function and the organization of lung tissues. In contrast, the left lung has only two lobes, which are the upper lobe and lower lobe. This difference in lobation is partly due to the space occupied by the heart, which shifts the left lung slightly to accommodate the heart's position in the thoracic cavity. Understanding these anatomical variations helps in various clinical practices, including interpreting imaging studies and performing procedures related to lung health.
