Why do molecules in the small intestine seem like they are disappearing?

• The molecules are getting absorbed into the blood

• The molecules are returning to the stomach

• The molecules are going to the large intestine

• The molecules are broken down and no longer exist

Why are some molecules absorbed into the blood stream, but some molecules are not?

• Some molecules are bigger than others.

• Some molecules are liquids.

• Some molecules are healthier for you.

• Some molecules are smaller than others.

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

• Her lungs are trying to supply more oxygen to her cells for chemical reactions to take place

• Her lungs are trying to bring carbon dioxide to her cells for chemical reactions to take place

• The cells in her body need glucose from the lungs for chemical reactions to take place
