Lungs of an Obese Male, Anterior View

Description

Positioned in anatomical stance, the thoracic cage is rendered semi-transparently to localize the respiratory tract within an obese adult male habitus. The trachea descends in the midline from the root of the neck to the carina, where the right and left main bronchi diverge inferolaterally into their respective lungs. Each lung occupies its pleural cavity lateral to the mediastinum, with blunt apices projecting superiorly above the level of the first rib into the neck root and broad bases resting on the domes of the diaphragm. Right and left hila sit medial, where bronchi and pulmonary vessels enter and exit. Obesity changes chest wall mechanics, and an anterior surface projection like this helps you teach why reduced functional residual capacity and basal atelectasis are common when supine or under general anesthesia. The blunt-appearing apices and the relationship of the lung bases to the diaphragm also matter when correlating physical exam and imaging: diaphragmatic elevation can mimic lower lobe volume loss, and anterior percussion and auscultation landmarks shift with increased abdominal mass. Intubation and bronchoscopy discussions also benefit from seeing the trachea and main bronchi centered against an obese torso, where neck soft tissue and altered head and neck positioning often complicate airway management. A practical view. Use this illustration for anatomy and respiratory physiology lectures, surface anatomy labs, and clinical skills teaching on breath sound mapping, diaphragmatic excursion, and obesity-related perioperative pulmonary risk. It also fits internal medicine and anesthesiology publications covering atelectasis prevention, incentive spirometry, and airway assessment in obese patients.
