Longitudinal and circular muscles. These are known as antagonistic muscles, meaning that one relaxes whilst the other contracts.
The digestive tract uses smooth muscle. If you compared it to thigh muscles, the thigh has striated muscle. Smooth muscle contracts and relaxes in a rhythmic manner, continually.

smooth muscle
In the walls of the tract organs
Smooth muscle tissue is the type of muscle tissue found in the walls of many organs and blood vessels in the body.
The 3 different types of muscle are smooth, cardiac, and skeletal muscle. Smooth muscle is located on the walls of hollow organs, cardiac muscle is located on the wall of the heart, and skeletal muscle is located on skeletal muscle organs (most organs). Their functions include movement in walls of hollow organs, pumping of blood, and movement of bones, heat production and posture, respectively. Cardiac and smooth muscle are involuntary, whereas skeletal muscle is voluntary. Both cardiac and skeletal muscles have striations, but smooth muscle does not.

Smooth Muscles
Digestive organs
Smooth muscle is involuntary tissue. It is not controlled by the brain. Smooth muscle forms the muscle layers in the walls of organs such as the lower part of the esophagus, stomach and intestines.
digestive tract
The food gets pushed through your digestive system by contaction in a ring of the smooth muscle in the walls of the various organs of the digestive tract (oesophagus, stomach, small and large intestine) and this is called peristaltism.
