Answer:
Less biological relevant model and reduce cell to cell interaction.
Explanation:
The two main disadvantages of a 2D model of the digestive system is that it is less biological relevant model and reduce cell to cell interaction. The 2D model does not show high resemblance to reality and this model also fail to show the interactions of two cell surfaces with each other. In short, this model, does not give us complete knowledge about any biological system.
