The wave-like contractions that propel food along the gut are called peristalsis. This involuntary muscle movement occurs in the digestive tract, helping to push food through the esophagus, stomach, and intestines. Peristalsis is essential for the proper digestion and absorption of nutrients.
Peristaltic movements are wave-like contractions of the muscles in the esophagus, stomach, and intestines that help propel food and nutrients through the digestive system. These movements are essential for moving food along the digestive tract and facilitating digestion and absorption of nutrients.
Oesophagus, portion of the digestive tube that conducts food from the mouth to the stomach. When food is swallowed it passes from the pharynx into the esophagus, initiating rhythmic contractions (peristalsis) of the esophageal wall, which propel the food along toward the stomach. Pharynx, area of the gastrointestinal and respiratory tracts which lies between the mouth and the oesophagus.
Peristalsis occurs to move food, liquids, and other substances through the digestive tract by contracting and relaxing the muscles in a wave-like motion. This process helps break down and propel food along the digestive system to facilitate digestion and absorption of nutrients.

Food is pushed through the digestive tract primarily by a process called peristalsis, which involves rhythmic, wave-like muscle contractions of the smooth muscles lining the digestive system. These contractions help to propel food from the esophagus to the stomach and through the intestines. Additionally, the secretion of digestive fluids and enzymes aids in breaking down food, facilitating its movement along the tract. Overall, this coordinated muscular activity ensures the efficient processing of food.
Peristalsis occurs mainly in the gastrointestinal tract, where it helps propel food along the digestive system through rhythmic contractions of the smooth muscle tissue in the walls of the organs, like the esophagus, stomach, and intestines.
Unicellular organisms move in a variety of ways. Paramecia have cilia, which are tiny hairs that act like oars and propel the organism along. Bacteria move by rotating a flagellum that looks a bit like oars and propel the organism These organisms "swim" along. An amoeba moves by changing shape and forcing its cytoplasm into extensions called pseudopods. - s delacruz
Peristalsis is the process by which smooth muscle moves a mass of food (called the food bolus) through the digestive system. There is circular smooth muscle and longitudinal smooth muscle in the digestive tract. Contraction of circluar smooth muscle keeps the food bolus from moving "backward" along the digestive tract by decreasing the diameter of the tract behind the bolus. Contraction of the longitudinal muscle in the digestive tract propels the food bolus "forward" in the digestive tract.
As a simplified response, muscles in the tongue pushes food into the pharynx. However, it's a little more complicated than that. This address has good info on your question: http://www.nature.com/gimo/contents/pt1/full/gimo1.html
It uses its 8 tentacles and thrashes them to propel through the water, like if you swam moving your arms to the sides
