A more specific term/compound word for an image that enumerates and shows the parts of something?

I was wondering if there is a more specific term for something like this:

Diagram of a heart

Diagram is the first thing that comes to mind, but I find it vague for there are different types of diagrams.

I also thought of anatomy, but I don't want to limit it to living things.

Thanks.


Solution 1:

That's an illustration of human heart.

Illustration: Something that serves to illustrate, such as a picture or diagram that helps make something clear or attractive. [M-W]
