What term describes the involuntary movements of circular and longitudinal muscles in the digestive tract?

Peristalsis refers to the coordinated, involuntary contractions of circular and longitudinal muscles in the digestive tract that propel food and liquid through the gastrointestinal system. This wave-like movement is essential for the proper functioning of the digestive tract, allowing materials to move efficiently from the esophagus to the stomach and through the intestines.

Peristalsis helps to ensure that food is moved along the digestive system smoothly and is a critical process for effective digestion and nutrient absorption. This rhythmic contraction is distinct from other digestive processes, emphasizing its role specifically in moving contents through the digestive tract rather than breaking down food (digestion) or absorbing nutrients.
