That is how the food gets from the mouth to the stomach.
No, the esophagus only functions in digestion. The trachea is the passageway for respiration.
The trachea lies ventral to the esophagus. The open part of the C-shaped rings faces the esophagus and this allows the esophagus to expand when swallowing.

The esophagus moves food via peristalsis, but no digestion occurs in the esophagus. It connects the mouth and stomach.

The esophagus has a physical break down. The esophagus squeezes the food down into the stomach, making this a physical break down.
