- What it is
- The largest right lobe, lying below and behind the oblique fissure and resting on the right dome of the diaphragm.
- Function
- Gas exchange; ventilated by the right lower lobe bronchus through a superior and four basal segments.
- Size
- About 25% of total lung volume; posteriorly it reaches the 10th rib.
- Clinical note
- Inhaled foreign bodies and aspirated material most often end up here, because the right main bronchus is wider and more vertical than the left.
