ANATOMY

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 teeth grind and chop food into tiny pieces while the glands in the mouth moisten it with saliva. Then the tongue pushes the moistened food, or bolus, to the back of the throat and down into the esophagus, which leads to the stomach.

Detailed explanation-4: -This is where digestive juices and enzymes break down the food that you chewed and swallowed. It prepares it to provide your body with energy. The stomach makes several digestive juices and enzymes that mix with food. Next, the stomach’s strong muscles act like a blender to turn food into a useable form.

Detailed explanation-5: -Esophagus: The esophagus is a muscular tube that connects the pharynx (throat) to the stomach. The esophagus contracts as it moves food into the stomach. A “valve” called the lower esophageal sphincter (LES) is located just before the opening to the stomach.
