Human Circulatory System Diagram - Anatomy & Blood Flow Explained #3324653 (License: Personal Use)

The image depicts a simplified yet accurate schematic of the human cardiovascular system, highlighting the dual-loop circulation: pulmonary (right heart to lungs and back) and systemic (left heart to body and back). Oxygen-poor blood is shown in blue traveling via veins to the right atrium, then pumped to the lungs; oxygen-rich blood returns via red vessels to the left atrium and is distributed systemically. Capillary beds in lungs and tissues are illustrated as green mesh networks where gas and nutrient exchange occurs.

Used in educational contexts-biology textbooks, medical training modules, health websites-to explain cardiovascular physiology. Matches user intent for learning anatomy, preparing for exams, or understanding heart function and circulation disorders.
