About this model

This anatomical heart is opened along its long axis, so you look straight into the chambers. The thick pink heart muscle frames both ventricles, whose inner walls show the ridged muscle texture, while pale valve leaflets and their tendon cords sit between atria and ventricles. On top, a red aortic arch with its three branches rises next to the blue pulmonary trunk and vena cava, following the textbook color code for oxygen-rich and oxygen-poor blood. The surface detail holds up in close-ups, which makes the model a strong fit for e-learning modules, animated explainers on circulation and medical visualizations, or as a source for your own lighter versions. Tip: place the camera in front of the cut and orbit slowly around the septum to show how the left and right heart are separated, or pair it with the human skeleton for a complete anatomy scene.

Good for

  • Biology lesson on blood circulation
  • Close-ups in medical explainer videos
  • Interactive anatomy quiz for e-learning
  • Science museum or AR exhibit

Engine import notes

Unity GLB · FBX

Import the GLB with the glTFast package or use the FBX. 1 m in the file = 1 Unity unit.

Unreal Engine FBX

Use the FBX. The model is built in metres. Unreal works in centimetres and converts on import, so it arrives at real size (0.13 m = 13 cm).

Godot 4 GLB · FBX

Drag the GLB into the FileSystem dock. Godot 4 imports it directly, with materials. The FBX works too (Godot 4.3+ imports it natively).

Blender BLEND · GLB

Open the .blend directly, or import the GLB via File › Import › glTF 2.0.

Use it in: UnityUnrealGodotBlender
