Complete Anatomy of the Right Lung

Description

Right lung anatomy is presented from an anterior orientation, with the apex projecting superiorly above the level of the first rib and the broad base resting on the right hemidiaphragm. The superior, middle, and inferior lobes are separated by the horizontal fissure and the oblique fissure, which course laterally and inferiorly to define the lobe boundaries on the costal surface. Medially, the contour implies the hilum region and mediastinal surface, where the pulmonary root would enter, while the anterior border descends toward the costomediastinal recess. Three-lobe morphology matters clinically because it changes both radiologic pattern recognition and surgical planning compared with the left lung. The horizontal fissure commonly produces a sharp line on chest radiographs and CT, and it also limits the spread of lobar pneumonia, so right middle lobe consolidation can be localized with confidence when the fissures are well formed. For thoracic surgeons, fissure completeness influences air leak risk during lobectomy and guides the choice between fissure-based dissection and a fissureless technique. Pulmonary anatomy plates like this support teaching of surface anatomy and lobar localization in gross anatomy, respiratory system modules, and radiology correlation labs. It also suits medical publishing content on right-sided lobectomy, bronchoscopy navigation, and segmental infection patterns in the adult thorax.
