Irregular peristalsis of digestive tract

The peristalsis of the digestive tract is not coordinated: the function of the digestive system is to digest and decompose the nutrients taken from the outside through the peristalsis of the digestive tract and the role of the digestive juice, and then absorb its nutrients and discharge the residues out of the body. The digestive system consists of two parts, the digestive tube and the digestive gland. The digestive tract includes the oral cavity, pharynx, esophagus, stomach, small intestine, and large intestine. It has a sports function, can accept, grind and stir food, and is fully mixed with digestive juices and continuously pushed toward the anus to drain its dregs. Digestive glands include salivary, gastric, intestinal, liver, and pancreas. The digestive juices they secrete can break down sugar, fat, and protein in food and turn them into substances that can be used directly in the body. The basic form of digestive tract movement is peristalsis. In the whole, the movement of the digestive tract is regulated by nerves (including transmitters released from various nerve endings) and hormones.
