Detailed explanation-1: -The movements of the tongue also massage small glands directly underneath it and squeeze out saliva. This starts pre-digestion of the food, and the bolus can glide down the esophagus more easily.
Detailed explanation-2: -Your tongue helps out, pushing the food around while you chew with your teeth. When you’re ready to swallow, the tongue pushes a tiny bit of mushed-up food called a bolus (say: BO-luss) toward the back of your throat and into the opening of your esophagus, the second part of the digestive tract.
Detailed explanation-3: -The Tongue Creates a Bolus so It Can Travel Down the Pharynx and Esophagus. The tongue manipulates the chewed food into a small mass called a bolus, then moves it to the oropharynx.
Detailed explanation-4: -Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
