The muscular wall of the left heart ventricle is considerably thickened and the tip of the heart is visibly rounded off. Highly detailed 2-part heart at a price you will love. The front heart wall is detachable to reveal the chambers and valves inside. The heart is just slightly smaller than life-size with exquisite anatomical detail throughout. Heart on removable stand.
