This high-resolution medical illustration depicts the human circulatory system in sagittal view, highlighting systemic and pulmonary circulation pathways. Arteries are shown in red (oxygen-rich blood), veins in blue (deoxygenated blood), with key structures including the heart, lungs, liver, kidneys, and major vessels like the aorta and vena cava clearly labeled. The semi-transparent skeletal and muscular overlays provide spatial context for vascular positioning.
