Detailed explanation-1: -Digestion begins in the mouth, well before food reaches the stomach. When we see, smell, taste, or even imagine a tasty meal, our salivary glands in front of the ear, under the tongue, and near the lower jaw begin making saliva (spit). As the teeth tear and chop the food, spit moistens it for easy swallowing.

Detailed explanation-2: -The digestive process starts in your mouth when you chew. 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. Esophagus.

Detailed explanation-3: -The statement “The esophagus is digestive in function” is true. The esophagus is a muscular hollow tube that connects the mouth to the stomach, making it the second major organ in the digestive system if ordering by function.

Detailed explanation-4: -The digestive process begins in the mouth. Even before eating begins, the anticipation of eating stimulates glands in the mouth to produce saliva.

Detailed explanation-5: -Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules. Digestion of food starts in the mouth. Saliva initiates digestion by converting starch into a simpler form.
