What are muscular movements along digestive tract?

The muscular movements along the digestive tract are called peristalsis and segmentation.

Peristalsis is a series of involuntary, coordinated muscle contractions that propel food and fluids along the digestive tract. Peristalsis occurs in the esophagus, stomach, and small intestine. It is a wave-like motion that begins in the upper part of the digestive tract and moves downward. Peristalsis helps to mix food with digestive juices and move it through the digestive tract.

Segmentation is a series of involuntary, non-propulsive muscle contractions that occur in the small intestine and colon. Segmentation helps to mix food with digestive juices and expose it to the intestinal walls for absorption. Segmentation also helps to move gas and waste products through the digestive tract.

Peristalsis and segmentation are essential for the proper functioning of the digestive system. They help to move food and fluids through the digestive tract, mix food with digestive juices, and expose food to the intestinal walls for absorption.
