Human Circulatory System Diagram - Anatomy & Function Overview #3487566 (License: Personal Use)

This schematic depicts the major pathways of the human circulatory system, highlighting systemic circulation from the heart through arteries to the extremities and back via veins. The heart is shown centrally with pulmonary vessels extending to the lungs (represented by the head outline), emphasizing dual circulation. Arteries are colored red (oxygenated blood), while veins are blue (deoxygenated), aiding visual learning.
