Answer 2

Small Intestine: Most hydrolysis of macromolecules occur in the small intestine. It is more than 6 meters in length. It has smaller diameter than that of the large intestine.  It is divided into 3 sections (Duodenum, Jejunum, and ileum).  

The lining of the small intestine has a surface area of 600m2 , about the size of a baseball diamond. Large folds are decorated with fingerlike projections called villi, and each of the epithelial cells has many microscopic appendages called microvilli. The nutrients, except fat, are absorbed into the capillaries, while the fat enters the lacteal. Only 2 single layers of epithelial cells separate the lumen from the bodies blood supply. In the center of the villus is a tiny lymphatic vessel called the lacteal.
