Detailed explanation-1: -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-2: -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.

Detailed explanation-3: -Once you put food in your mouth, close your lips and begin chewing. Use your tongue to move the food from one side of your mouth to the other. The jaw should slightly rotate while chewing. Don’t overload your mouth.

Detailed explanation-4: -They are your largest and flattest teeth. Your molars are the workhorses in your mouth. They mash, grind, crush and chew food with saliva and digestive enzymes until it is ready to swallow.
