my mouth, because how can we chew without a mouth

Answer:

1.Mouth

2.esophagus

3.deglutition

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.

2.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. There, it mixes with more digestive enzymes to continue the breakdown process.

3.Swallowing, also called Deglutition, the act of passing food from the mouth, by way of the pharynx (or throat) and esophagus, to the stomach.
