    All of this absorption and much of the enzymatic digestion takes place on the surface of small intestinal epithelial cells, and to accomodate these processes, a huge mucosal surface area is required. Brush border enzymes take over from there. Other brush border enzymes are maltase, sucrase, and lactase. A distinctive feature of the jejunum and ileum is the lack of glands in the submucosa.

    In the jejunum, the submucosa shows no typical characteristics whereas the ileum contains aggregations of lymphoid follicles termed Peyer's patches. The main function is to supply the body with water, electrolytes and nutrients from ingested food.
