Muscularis externa Consists of two smooth muscle layers. This is for increased surface area for the maximum aborbsion by the small intestine. Describe the structure of the interior surface of the small intestine and explain how this structure relates to its function.

These projections increase the surface area for absorption. The small intestine is a windingtightly folded tube about 20ft6m long in adultsIt connects to the stomach on the top end and to the large intestine colon on the bottom endMost of the food a person consumes is digested and absorbed in the small. Mucosa Innermost layer Contains the epithelium lamina propria and muscularis mucosae.
