ANATOMY

Detailed explanation-1: -After ingestion, the solid hard materials are broken down into smaller pieces or chewed with the help of teeth. These food materials get mixed with the digestive juice called saliva secreted from the salivary gland by the movement of the tongue. Thus, this moist mixture forms ball-like structures called a bolus.

Detailed explanation-2: -bolus, food that has been chewed and mixed in the mouth with saliva. Chewing helps to reduce food particles to a size readily swallowed; saliva adds digestive enzymes, water, and mucus that help chemically to reduce food particles, hydrate them for taste, and lubricate them for easy swallowing.

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: -Swallowing: Ingestion 2 The food is formed into a small ball called a bolus, which is pushed to the back of the mouth by the tongue. Involuntary muscle contractions in the pharynx then push the bolus down towards the oesophagus.

Detailed explanation-5: -The food that gets chewed and mixed up with saliva is termed a bolus. The acidic fluid consisting of gastric juices and partly digested food that passes from the stomach to the small intestine is known as chyme.
