What is one limitation of a using a 2D computer-generated image of the digestive system instead of using the actual thing? (1 point)
Responses

The 2D image is less accurate in showing how the organs look, such as their texture.

The 2D image does not show all of the organs since some of them overlap.

The 2D image is too small and the organs are, therefore, difficult to see.

The 2D image is messy and does not show how the organs are connected to each other.

One limitation of using a 2D computer-generated image of the digestive system instead of using the actual thing is the 2D image does not show all of the organs since some of them overlap.
