Questions to Ponder (Part 1)

1. What are the end-products of carbohydrate, protein and fat digestion?

2. Why do these large, complex nutrients need to be digested?

(Part 2)

1. As food passes through the different sections of the alimentary canal, food is digested. Food is completely digested by the time it reaches the ileum. What do you think will happen if the digested nutrients continue to pass through the remaining parts of the human digestive system?

2. Therefore, can you name the process happening at the ileum?
