Detailed explanation-1: -The term bolus applies to this mixture of food and solutions until they are passed into the stomach. Once the bolus reaches the stomach, mixes with gastric juices, and becomes reduced in size, the food mass becomes known as chyme .
Detailed explanation-2: -Mechanical digestion in the oral cavity consists of grinding of food into smaller pieces by the teeth, a process called mastication. Chemical digestion in the mouth is minor but consists of salivary amylase (ptyalin, or alpha-amylase) and lingual lipase, both contained in the saliva.
Detailed explanation-3: -In digestion, a bolus (from Latin bolus, “ball") is a mass of food that (with animals that can chew) has been chewed at the point of swallowing.
Detailed explanation-4: -Abstract: The first step in the digestion process is mastication, or chewing, when food is broken down, lubricated with saliva, and formed into a cohesive mass known as the food bolus. Upon swallowing, the bolus moves to the stomach and undergoes further breakdown during gastric digestion.
