Resin cast of human heart blood vessels!!! This model was achieved by injecting liquid plastic into a real heart. The plastic resin fills the blood vessels and, once the resin sets, the tissue is dissolved away leaving a perfect replica of the blood supply of the heart! An absolutely marvelous view❤️
