Answer 2

Answer:

Digested nutrients pass into the blood vessels in the wall of the intestine through a process of diffusion. The inner wall, or mucosa, of the small intestine is lined with simple columnar epithelial tissue.Structurally, the mucosa is covered in wrinkles or folds called plicae circulares.The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients.The absorbed substances are transported via the blood vessels to different organs of the body where they are used to build complex substances, such as the proteins required by our body.
