As food enters the esophagus, your salivary glands release a rush of saliva to help food slide more easily down the tube.Then your esophageal muscles swing into action.Like the rest of your digestive tract, your esophagus is ringed with muscles that contract to produce wavelike motions â which you can refer to as peristalsis or (no surprise here) peristaltic contractions, if you're so inclined â pushing food down toward your stomach.igesting food is a two-part process that's half mechanical, half chemical. 1  Mechanical digestion begins in your mouth as your teeth tear and grind food into small bits and pieces you can swallow without choking. 2  Chemical digestion occurs at every point in the digestive system, beginning when you see or smell food.
