Bolus Definition:
After food is deemed acceptable and chewing commences, tongue movements manipulate the mixture of saliva and food, helping shape it into a ball called a bolus.

Bolus Notes:
A bolus is a ball-like mixture of food and saliva that forms in the mouth during the process of chewing. Once the bolus reaches the stomach, it mixes with gastric juices and becomes chyme, which then travels through the intestines for further digestion and absorption, and eventual discharge as feces. It has the same color as the food being eaten, and the saliva gives it an alkaline pH. Under normal circumstances, the bolus is swallowed, and travels down the esophagus to the stomach for digestion.
