the muscles are smooth muscles!
They are involuntary muscles.
It's the muscles that compose organs.
peristalsis
There are three types of muscles found in the human body. The muscles found in the body are the visceral, cardiac, and skeletal muscles.
Skeletal, cardiac, and smooth (visceral).
Peristalsis is the wavelike motion of muscles that pushes food downward through the digestive tract. It helps propel food and liquids from the esophagus to the stomach and through the intestines for digestion and absorption.
Muscles are made up of "excitable cells" which can contract. Visceral muscle is smooth muscle--one of three types of muscles in the body. Visceral muscle is found in the body in places like the arteries, bladder, the digestive tract and many other muscles which need to contract in order to perform their job.
Insect muscles are divided into four categories: visceral, segmental, appendicular, and flight. Visceral muscles are associated with the digestive system, segmental muscles are used to assist in molting, maintain body pressure by increasing it, and in larvae, move. Appendicular muscles move any appendages, often as a single unit. Flight muscles are specialized and capable of rapid contractions.

Peristalsis - the wavelike motion of the intestinal wall smooth muscles that push the food forward.
muscles lining the esophagus move in a wavelike motion, oushing the food through the esophagus and into the stomach
