Esophagus
The esophagus is the part of the alimentary canal that is involved in pushing down food from the mouth to the stomach. It is a muscular tube that connects the throat (pharynx) with the stomach.

Peristalsis
The process of pushing down food through the esophagus is achieved through a series of muscular contractions known as peristalsis. Peristalsis is a coordinated, wave-like movement of muscles that helps propel food downwards.

Upper Esophageal Sphincter
At the upper end of the esophagus, there is a muscular ring called the upper esophageal sphincter that opens to allow food to enter the esophagus from the mouth.

Lower Esophageal Sphincter
At the lower end of the esophagus, there is another muscular ring called the lower esophageal sphincter that opens to allow food to pass from the esophagus into the stomach.

Role in Digestion
The esophagus plays a crucial role in the process of digestion by transporting food from the mouth to the stomach where further digestion can take place. It ensures that food is moved efficiently and safely through the digestive tract.
