  • The jejunum and ileum finish chemical digestion and absorb most of the nutrients.
  • Folds and projections in the small intestine’s wall increase the surface area for absorption.

What are the three parts of the small intestine and do each of these 3 parts have different functions?

What are the regions of the small intestine in order starting with the first region after the stomach?
