This geometry node modifier procedurally generates simplified schematics of blood vessels. It includes customizable controls to add or strip away vessel layers and create cutaway views for anatomical illustrations. The setup is designed specifically for arteries and capillaries, as it does not include the valve structures required to depict veins.

The tool provides built-in options to populate the interior of the vessel with red blood cells, white blood cells, and platelets. You can also bring the internal flow to life using the included animation controls, which handle both the motion and rotation of these cellular components within the bloodstream.
