yes, Muscularis mucosa - The stomach and small intestine's mucosa are pulled into undulating folds by a thin layer of smooth muscle that is constantly tensed. The surface area that is available for digestion and absorption is significantly increased by these folds.
The submucosa is located directly beneath the mucosa, as its name suggests. It joins the underlying muscularis to the overlaying mucosa by way of a large layer of dense connective tissue. It has blood and lymphatic vessels (which carry nutrients that have been absorbed), as well as a few submucosal glands that secrete digestive juices. Additionally, it functions as a passageway for the submucosal plexus, a densely branched network of nerves.
These layers compress to encourage mechanical digestion, expose more of the food to the chemicals that aid in digestion, and transport the food along the canal.
