What is the primary role of the esophagus?

The primary role of the esophagus is to transport food from the mouth to the stomach. This muscular tube connects the throat (pharynx) to the stomach and plays a crucial role in the digestive process. When a person swallows, food moves into the esophagus, which uses coordinated muscle contractions, known as peristalsis, to push the food downward into the stomach.

This function is essential for the sequential process of digestion, where food is first ingested, then transported, and finally broken down in the stomach and intestines. The esophagus does not play a role in digesting food, absorbing nutrients, or producing saliva; these functions are managed by other parts of the digestive system.
