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

This high-resolution medical illustration depicts a sagittal cross-section of the human thorax, showcasing the bilateral lungs, central heart, ascending aorta, pulmonary trunk, superior vena cava, and visible coronary arteries. The pericardial sac is partially opened to expose the heart’s chambers and surface vasculature, while the pleural cavities are shown enclosing each lung. Color-coding distinguishes oxygenated (red) and deoxygenated (blue) blood pathways.

Used in medical textbooks, online anatomy courses, patient education materials, and clinical presentations to explain cardiopulmonary anatomy and spatial relationships; targets students, healthcare professionals, and informed patients seeking visual understanding of thoracic structures.
