The cardiovascular system represents a complex network of blood vessels that transport essential nutrients, oxygen, and waste products throughout the body. This detailed illustration demonstrates the hierarchy of blood vessels, from major arteries and veins to microscopic capillaries, showing how blood circulates from the heart to tissues and back. The diagram uses color coding to distinguish between oxygen-rich (red) and oxygen-poor (blue) blood vessels.
The human circulatory system is an intricate network that extends throughout the entire body, carrying vital oxygen and nutrients to every cell. This comprehensive illustration combines a full-body view of the circulatory system with detailed heart anatomy, showing both external and internal perspectives of blood flow. The diagram uses blue to indicate deoxygenated blood vessels and red for oxygenated blood vessels, clearly demonstrating how blood circulates through the body and heart.
