the mouth has salivary glands to help the food go down the esophagus easier
Yes there is, because chemical is the saliva and you swallow the saliva.

saliva
Saliva breaks down your food as you chew, softening it and making it smaller. It also lubricates the esophagus.
Food moves from the mouth to the stomach through the esophagus. A combination of gravity and small muscles in the esophagus causes the food to move.
i saliva does not reach the stomach, it gets broken down in the esophagus!

Yes saliva is used to help turn the food into a substance which is able to slide down the esophagus. Salivary glands produce the saliva in the mouth however; the saliva does help to digest the food slightly in order for it to be moved by peristaltic waves. The main function of the esophagus is to move the food, but it will have been slightly digested.
Saliva is produced by the salivary glands in the mouth and is swallowed. It helps with digestion by moistening food and beginning the breakdown process with enzymes. After swallowing, saliva travels down the esophagus and into the stomach.
The esophagus is merely a tube that transports foods and liquids to the stomach. While enzymes in saliva break down food, the esophagus plays no role in separating or breaking down food molecules.
The Esophagus has 9 specific layers, if you are healthy. They are: mucosa, saliva, lamina propria, smooth muscle, papillae, muscularis extenma, striated muscle, and adventa.
You break it down by chewing it and while you're doing that, your saliva will help dampen the food. Once it is small enough, you swallow it and it travels down through your esophagus. Your nutrients are absorbed while it travels, not while it is in the esophagus.
