2. the stomach - by the muscular contractions of the walls in the stomach called peristalsis.

Esophagus, also known as the food pipe, is a primary food conduit through which the food passes from the pharynx to the stomach. The movement of food in the food pipe is aided by the peristaltic contractions.
