HUMAN NUTRITION

Detailed explanation-1: -In digestion, a bolus (from Latin bolus, “ball") is a ball-like mixture of food and saliva that forms in the mouth during the process of chewing (which is largely an adaptation for plant-eating mammals). It has the same color as the food being eaten, and the saliva gives it an alkaline pH.

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. Under normal circumstances, the bolus then travels down the esophagus to the stomach for digestion.

Detailed explanation-4: -A bolus (from the Latin bolus or “ball”) was defined here broadly as an individual volume of food in the stomach that was distinguishable in the images from the surrounding liquid or chime.

Detailed explanation-5: -Mastication (chewing), in which food is crushed and mixed with saliva to form a bolus for swallowing, is a complex mechanism involving opening and closing of the jaw, secretion of saliva, and mixing of food with the tongue.
