3D Human Heart Model
CC0Free for commercial use — no attribution needed.
Life-size educational 3D model of the external human heart, approximately 11 × 8.3 × 15.6 cm. Depicts the ventricular myocardial envelope, right and left atria and auricular appendages, ascending aorta and aortic arch with its three major branches, superior and inferior vena cava, pulmonary trunk and right and left pulmonary arteries, four pulmonary veins, and branching coronary arteries and cardiac veins. Textured red-brown myocardium and subtly differentiated arterial and venous materials support external anatomical study. Major cut vessels feature wall thickness and visible lumens. Structures are named for inspection. External-surface representation, not an internal chamber or valve cutaway; intended as an educational visualization, not a clinical or surgical reference.
