Heart · Detail mode3D external view · 3D cross-section · 2D explanation

3D cross-section: animated heart model in the Sketchfab viewer · rotate and zoom directly in the model

Anatomy Blood flow

Heart anatomy with labelled external structures

deoxygenated bloodoxygenated blood

Blood flow through the heart with atria, ventricles, valves and great vessels

Loading heart detail view

A high-detail 3D heart model with an external view, dedicated cross-section and 2D explanation mode is being loaded.

Left mouse: rotate · Mouse wheel: zoom · Right mouse: pan · Select a heart structure in the information panel · the 3D model remains unchanged

Left mouse: rotate · Mouse wheel: zoom · Right mouse: pan · Click a vessel or heart structure · the translucent body reference is for orientation only

Loading cardiovascular system

The high-detail 3D model of arteries, veins and the heart is being prepared with a translucent body reference.

Left mouse: rotate · Mouse wheel: zoom · Right mouse: pan · Click an organ · the translucent body reference is for orientation only

Loading organ systems

The high-detail organ systems, including the heart, are loaded from a shared anatomical atlas, precisely aligned and rendered with organ-specific materials.
