Esophagus vs. Trachea: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Esophagus is a muscular tube that conveys food from the throat to the stomach. Trachea is the windpipe, a tube carrying air to and from the lungs.
Key Differences
The esophagus serves as a passage for food and liquids from the mouth to the stomach. The trachea, also known as the windpipe, is a vital part of the respiratory system, conducting air to and from the lungs.
