ANATOMY

Detailed explanation-1: -Mouth. 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.

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: -Food is masticated by teeth and moistened by saliva secreted from the (b) salivary glands. Enzymes in the saliva begin to digest starches and fats. With the help of the tongue, the resulting bolus is moved into the esophagus by swallowing.

Detailed explanation-4: -After you chew and swallow your food, it enters your esophagus. This tube connects your throat to your stomach. A series of muscular contractions, known as peristalsis, pushes your food downward and into your stomach.

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.
