When you eat, what happens to the fiber in your food?

• Fiber is broken down into starch molecules and absorbed

• Fiber is too big to be absorbed, so it is excreted as solid waste

• Fiber is broken down into glucose and absorbed

• Fiber is coming together and getting bigger. Then it is absorbed.

Why is Amaya having shortness of breath from a digestive system disease?

• She is out of shape from lack of activity
