Study Notes
Gastrointestinal Tract Movements
- Propulsion of food towards the anus is primarily achieved through peristalsis, a wave-like muscle contraction.
- The gastrointestinal tract exhibits a complex pattern of movements known as motility, which facilitates digestion and transportation of contents.
- Segmentation is the movement responsible for mixing intestinal contents, especially when forward progression is halted by a sphincter. This movement allows for enhanced nutrient absorption.
- Local constrictive contractions occurring every few centimeters in the gut wall are referred to as mixing contractions or segmental contractions, which help to mix digested food with digestive juices.
- Receptive relaxation in the gastrointestinal tract enables the stomach to accommodate food without a significant increase in pressure, facilitating smooth passage of contents and maximizing storage capacity.
