The stomach has three layers of muscle, known as the muscularis externa, which consist of an outer longitudinal layer, a middle circular layer, and an inner oblique layer. These layers work together to facilitate the mixing and churning of food, aiding in digestion. The coordinated contractions of these muscles help propel the food through the stomach and into the small intestine. This unique arrangement allows for effective mechanical digestion.
