Peristalsis. The movement of muscles bringing the food to the stomach.
I believe it does mechanical breakdown because the esophagus muscles push down the food which would be mechanical breakdown.
It carries food from the mouth to the stomach.
No digestion occurs in the esophagus -- neither chemical nor mechanical.
The only job the esophagus has is to get the food from the mouth to the stomach. There is no chemical digestion going on there.
CHEMICAL
chemical
No chemical or mechanical digestion occurs in the esophagus, only propulsion, which is one of the six digestive processes.
While the pharynx and esophagus do not perform any mechanical or chemical digestive processes, they provide a critical service for the digestive system. They move food from the mouth to the stomach.
Saliva begins the chemical digestion of starch. It also is important for the success of mechanical digestion of the mouth, but does not, in its own, perform mechanical digestion.
Both the mouth and the stomach perform mechanical and chemical digestion.
The small intestine completes the process of chemical digestion.
The mechanical process of digestion is first, followed closely by chemical digestion. After that it is mostly chemical digestion, then absorption, and lastly elimination, or defecation.
The mouth is the beginning of both mechanical and chemical digestion. Chewing breaks the food into smaller pieces and the saliva wets the food but also adds an enzyme called amylase that begins the digestion of carbohydrates.
No, the esophagus only functions in digestion. The trachea is the passageway for respiration.

Chewing is mechanical digestion.
