The correct response that highlights a disadvantage of using a dissected pig compared to a 2D model of the human digestive system is:
A dissected pig’s inner structure is slightly different than a human’s.
This option emphasizes that while pigs and humans have some anatomical similarities, the differences in their inner structures can lead to challenges in applying findings from pig anatomy directly to human physiology. The other options do not accurately convey a relevant disadvantage in this context.
