Human Thoracic Anatomy Diagram: Esophagus, Trachea, Aorta & Diaphragm #97931 (License: Personal Use)

This black-and-white medical illustration depicts the vertical alignment of major thoracic structures: the esophagus posterior to the trachea, the aortic arch curving over the left main bronchus, and the diaphragm forming the inferior boundary. Fine hatching and cross-sectional views emphasize spatial relationships critical for understanding respiratory and digestive anatomy. The dashed midline suggests a sagittal plane for orientation.

Used in medical textbooks, anatomy courses, and healthcare training materials to teach thoracic organ relationships; targets students, clinicians, and educators seeking visual reinforcement of core anatomical concepts.
