Most animators don’t create internal organs for characters because, in most productions, there’s no need to show them. Modeling organs takes extra time, effort, and budget, so if the story doesn’t involve things like surgery or dismemberment, they simply aren’t included.
In both 2D and 3D animation, characters are usually built with just an outer mesh (the visible body), a rig (digital skeleton for movement), and facial controls. Internal anatomy is only created when the scene specifically requires it, such as in medical shows, horror content, or certain video games.
