This detailed anatomical illustration presents two complementary views of the human heart, showcasing its external structure and coronary circulation system. The side-by-side comparison effectively demonstrates both the major vessels and chambers alongside the intricate network of coronary vessels that supply the heart muscle itself, using clear color differentiation between oxygenated and deoxygenated blood pathways.

The pelvic skeletal system represents a complex architectural masterpiece of human anatomy, serving as the foundation for both mobility and stability. This comprehensive anterior view illustration details the intricate components of the human pelvis, showcasing the various bones, joints, and anatomical landmarks that work together to support the upper body, protect internal organs, and facilitate movement of the lower extremities.

This detailed anatomical illustration presents a comprehensive view of the human heart against a deep blue background, highlighting its complex network of blood vessels, chambers, and crucial structures. The diagram employs effective color coding - red for oxygen-rich vessels and blue for deoxygenated blood pathways - making it an invaluable educational resource for understanding cardiac anatomy.
