I'm new to blender and I have learned some basic animating features. I have taken a video project for a school in which I have to explain the digestive system in a fully animated way.
I have modeled the Digestive system. Now when the food enters mouth and goes through esophagus(food pipe) esophagus creates a pushing wavy movement to push the food to stomach.
Could you suggest some easy ways to animate it?
This picture explains the process of peristalsis.
