Segmentation is a muscle action that mixes chyme with digestive juices, while Peristalsis is a muscle action that moves food through the digestive system.
Small intestine
The stomach mixes food, swallowed saliva, and gastric juices into a substance called chyme.
The muscle action that mixes chyme with digestive juices throughout the digestive system is called Peristalsis. Peristalsis are wave-like of contractions and expansions of muscles. The muscles help to move the bolus (food) through the digestive tract. Peristalsis are located all over the digestive tract.
The small intestine. The mouth mashes food with the teeth and mixes it with saliva which also includes some acid compounds.
Segmentation in the digestive tract mixes food with digestive juices and increases the rate of absorption by repeatedly moving different parts of the food mass over the intestinal wall.
Digestive juices is produced in the stomach and small intestine. The mouth does not produce digestive juices, it is only saliva. The food will stay in the stomach for 2-5 hours and digestive juices are added to make it softer and then, the food travels to the small intestine where more digestive juices are added.
The stomach because it stores and mixes food. Stomach- pouch shaped organ that has gastric juice, and stores and mixes food.
The digestive juices
The muscularis externa is the layer of the digestive tube, which consists of smooth muscles. It mixes ingested food with gastric juices so digestion is able to occur.
