The food travel down to the oesophagus through the process of peristalsis i.e. the contraction and relaxation of muscles. As we know the length of food pipe is 25 cm. Therefore peristalsis takes place in order to pass the food into the stomach.
Remember: This process is applicable to human digestive system.
