Left and Right Lung Differences: Lobes, Size, Hilum, and Heart Proximity

Key Differences

  • Right lung: Larger, three lobes, has hilum (entry/exit for bronchi, vessels, nerves).
  • Left lung: Smaller, two lobes, no hilum—has aortic window; closer to heart, slightly shorter, smaller diameter.

Differences due to heart occupying left side of chest, requiring left lung to be smaller.
