Right Lung and Diaphragm, Lateral View

Description

Right thoracic anatomy is presented in lateral profile, with the costal surface of the right lung draped over the domed diaphragm. The horizontal fissure runs anteroinferiorly from the hilum region to separate the superior lobe from the middle lobe, while the oblique fissure descends posteroinferiorly to demarcate the lower lobe. Superiorly, the trachea with its C shaped cartilaginous rings continues toward the carina, and the proximal right main bronchus would lie just anterior to the esophagus and enter the lung at the hilum, deep to the visceral pleura. Pleural recesses frame the lung base. Lateral orientation matters because it matches how clinicians think during chest tube placement and thoracentesis, where the diaphragm’s superior excursion and the costodiaphragmatic recess determine safe needle trajectory. Right sided processes also behave differently: aspirated material and post obstructive pneumonias often track into the right lower lobe because the right main bronchus is shorter, wider, and more vertical than the left. Diaphragmatic mechanics belong in the same frame. A raised hemidiaphragm in phrenic nerve palsy, postoperative atelectasis at the lung base, or a subpulmonic pleural effusion can all be reasoned through by tracking the lung’s inferior border against the muscular dome. Use this artwork for gross anatomy teaching of lobes and fissures, respiratory physiology modules on ventilation, and clinical skills materials that pair surface anatomy with pleural procedures on the right hemithorax. It also suits surgical education for lateral approaches such as VATS port planning and for publisher figures comparing lobar distribution of pathology on chest radiography.
