Human Cardiovascular System Diagram - Anatomy & Circulation Overview #3623208 (License: Personal Use)

This stylized medical illustration depicts the central cardiovascular structures within a human torso silhouette, including the four-chambered heart, major arteries (aorta, pulmonary artery), and systemic/venous return vessels. Red vessels represent oxygen-rich arterial flow, while blue denotes oxygen-poor venous circulation, with branching networks shown in the lungs, arms, and abdomen. The diagram emphasizes structural relationships rather than precise anatomical scale.

Used in educational websites, biology textbooks, healthcare patient portals, and anatomy learning modules to visually explain blood circulation, heart function, and vascular anatomy; targets students, educators, and patients seeking foundational cardiovascular knowledge.
