Gastric mixing is facilitated by:

Discontinuous Circular smooth muscle, Tenae coli & Haustra

One layer each of Oblique, Circular, & Longitudinal smooth muscles

An equal mix of skeletal and smooth muscle layers

Cardiac & Pyloric Sphincters

Gastric mixing is primarily facilitated by one layer each of oblique, circular, and longitudinal smooth muscles. The stomach has a unique arrangement of these three muscle layers, which allows for effective churning and mixing of food with gastric juices, aiding in the digestive process. The oblique layer, in particular, helps with the mechanical breakdown of food, along with the circular and longitudinal layers that contribute to peristalsis and mixing.
