The esophagus connects the pharynx and the stomach. According to the reference, your esophagus is located behind your trachea and it "passes food and liquid from your pharynx to your stomach."
The Esophagus' Role
The esophagus is a muscular tube that plays a vital role in the digestive system. Its primary function is to transport ingested food and liquids from the pharynx, located at the back of the throat, to the stomach, where digestion begins.

How the Esophagus Works
- Peristalsis: The esophagus utilizes a process called peristalsis, which are muscular contractions that push food down towards the stomach.
- Muscular Tube: This muscular tube ensures food and liquids are moved efficiently and effectively through the digestive system.
- Sphincters: The esophagus contains two sphincters which are circular muscles, the upper and lower esophageal sphincter, which are involved in preventing food from going back up the esophagus.
