What is propulsion in Digestive System?

Propulsion in the digestive system refers to the movement of food through the digestive tract, primarily achieved through muscular contractions known as peristalsis. This coordinated contraction and relaxation of smooth muscles help push food from the esophagus through the stomach and into the intestines. Additionally, segmentation, a form of contraction in the intestines, mixes food with digestive juices, aiding in nutrient absorption. Together, these processes ensure that food is efficiently processed and moved along the digestive system.
