How Does Propulsion Occur in the Digestive System?
In the digestive system, propulsion primarily involves the process of peristalsis:
- Peristalsis: This is a series of wave-like muscle contractions that move food through the digestive tract. The inner circular and outer longitudinal layers of smooth muscle work in coordination to create these waves. - Segmentation: In addition to peristalsis, segmentation contractions mix the contents to enhance digestion and absorption.
