Recall challenge Question 1 of 8

Select the chamber that receives oxygen-poor blood returning from the body.

Select a structure in the model or outline.

Second viewport / proof

The model is not the lesson.
The relationship is.

Canvas, outline, notes, URL state, and receipt all follow the same selection. Use the outline when a spatial mark is occluded or a precise pointer is unavailable.

Interactive educational model of typical human heart anatomy. Structures, proportions, route-authored flow paths, materials, and flow timing are simplified and schematic; anatomy also varies between people. Not diagnosis or treatment advice.
