Answer:
By the contraction of the muscles cells of oesophagus.
Explanation:
The oesophagus is a long tube-like structure of the digestive system. No digestion takes place in the oesophagus. It is next part to the mouth in the alimentary canal and it is lack of any enzyme but when food reaches the oesophagus, it helps to move the food into the stomach by the contraction of muscles of oesophagus. This contraction of muscles is known as peristalsis. In this process, epithelial cells secrete mucus which makes the food smooth by which food can easily move toward the stomach.
