And as we'll see in just a moment at the brush border, we have digestion and absorption taking place. So as we mentioned earlier, inside our dudum, we basically have our digestion taking place. So the cells inside this region are capable of producing our proteolytic enzymes that break down our polysaccharides, the polypeptides as well as lipids. On top of that, the brush border found in the dudenum also contains proteolytic enzymes that are attached onto the membrane of denterasides. So when those macromolecules approach these microvilli of anterosos, that membrane of these intellicides contains these proteolytic enzymes that can break down the macromolecules into smaller units. Now, in addition, we have specialized types of exocrine organs, exocrine glands in the human body, and one is aropankreas.
