Propulsion is the movement of food down the esophagus and peristalsis is the contractions in the stomach walls that moves food through the digestive tract.
A bolus is formed in the mouth and travels through the whole digestive system of a human.
Peristalsis is the process by which smooth muscle moves a mass of food (called the food bolus) through the digestive system. There is circular smooth muscle and longitudinal smooth muscle in the digestive tract. Contraction of circluar smooth muscle keeps the food bolus from moving "backward" along the digestive tract by decreasing the diameter of the tract behind the bolus. Contraction of the longitudinal muscle in the digestive tract propels the food bolus "forward" in the digestive tract.
The bolus is not an organ or anything in your digestive system. its a term for the ball of food that accumulates in your mouth so it can be moved down the esophagus
The esophagus is a muscular tube that only transports food and liquids from the mouth to the stomach through a series of contractions called peristalsis. Its main function is to propel food bolus to the stomach for further digestion and absorption.

The term is peristalsis. This refers to smooth muscle tissue contracting rhythmically to move food (bolus) through the intestines.
Bolus goes down esophagus, through lower esophageal sphincter (aka, cardiac sphincter) and into stomach. (A sphincter is a circular muscle which squeezes shut or opens the tubular digestive tract). It then passes through pyloric sphincter into small intestine. The small intestine is made up first of the duodenum, then jejunum, then ileum. From ileum, bolus goes to ascending colon, then transverse colon, then descending colon. From there to rectum and then out through anus (anal sphincter) .
It Is used to carry the bolus of food from the mouth to the stomach.
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.
A bolus (of food, for instance) passes through the esophagus.
The muscles responsible for propelling a food bolus down the length of the pharynx to the esophagus include the pharyngeal constrictor muscles, the inferior pharyngeal constrictor muscle, and the esophageal sphincter muscles. These muscles contract in a coordinated manner to help move food through the digestive tract.
