The waves of muscular contractions that propel the contents of the digestive tract toward the anus are called peristalsis. Peristalsis is a series of wave-like muscle contractions that move food along the digestive tract. This process begins in the esophagus when food is swallowed and continues through the stomach and intestines. The muscles in the walls of these organs contract and relax in a coordinated manner, pushing the contents forward.

Peristalsis is crucial for digestion and absorption of nutrients, ensuring that food does not just sit in one area of the digestive system but is rather continuously moved along. This action also helps in mixing the food with digestive enzymes, facilitating the breakdown and absorption of nutrients. If there are any disruptions to this process, it can lead to gastrointestinal issues.
