Human Thoracic Anatomy Diagram - Lungs, Heart, and Major Vessels #1203200 (License: Personal Use)

This high-fidelity medical illustration depicts a sagittal cross-section of the human thorax, revealing the heart centrally positioned between the left and right lungs. Major vascular structures-including the ascending aorta, pulmonary trunk, superior vena cava, and coronary arteries-are color-coded (red for oxygenated, blue for deoxygenated blood) to clarify circulation pathways. The pericardial sac and pleural membranes are also shown to emphasize spatial relationships and protective layers.

Used in anatomy textbooks, online medical courses, and patient education materials to explain cardiopulmonary structure and function; supports learning about congenital defects, surgical approaches, or respiratory-cardiovascular integration.
