The circular muscle layer prevents food from traveling backward and the longitudinal layer shortens the tract.

The function of the projections of the mucosa of the GI tract is secretions and absorption. Digestion is also aided by these projections.

The stomach has the strongest muscles in the gastrointestinal tract. These muscles are responsible for churning and breaking down food for digestion.
These waves of in the smooth muscles in the GI tract are call peristalsis.
Peristalsis Peristaltic contractions
The rhythmic movement of muscles in the walls of the gastrointestinal (GI) tract is called peristalsis. It helps propel food and nutrients through the digestive system by contracting and relaxing muscles in a coordinated manner. This movement is essential for digestion and absorption of nutrients.
The walls of the GI tract are composed of four main layers of tissue: mucosa, submucosa, muscularis, and serosa. Each layer has a specific function that contributes to the digestive process.
The stomach has the thickest walls and the strongest muscle in all the GI tract organs. : )
Circular muscles are called sphincters, there are many different sphincter muscles in the human body.
