Question

What is peristalsis?

Answer 1

Hint: When a bolus of liquid or food goes to your esophagus then this movement is known as peristalsis. This peristalsis movement is started from the mouth and directly goes to the stomach via the esophagus.

Complete answer:
Peristalsis mostly is a series of wave-like muscle contractions that move food to different processing stations in the digestive tract. The peristaltic movement, also called the peristalsis, refers to the contraction and relaxation of the muscles in the esophagus and the food pipe. Thus, the food specifically is forced down the track to the stomach, which mostly is quite significant.
The process of peristalsis begins in the esophagus when a bolus of food for the most part is swallowed. The peristaltic movement is initiated from the esophagus when the food specifically is completely swallowed which includes the reflexive action of the longitudinal and circular muscles greatly in the digestive sites, and some other times in fairly hollow tubes that are kind of present in actually as progressive wave-like contractions. Hence, this further shows how this movement is involuntary and is necessary for the movement of food down the stomach, passing down the anus at last.

Note:
Esophagus is a part of the digestive system where the beginning of peristalsis occurs, and the food is thus sent to the stomach. During this process, many wave-like muscle contractions take place in many series which transfers the food to many different stations for processing in the digestive tract. In the process, all muscle contractions concerned with the involuntary movements, circular muscles are involved.
