IPA: /ɪˈsɒfəɡəs/
KK: /ɪˈsɑfəgəs/
A muscular tube in the body that carries food from the throat to the stomach.
When you swallow, food travels down the esophagus to reach your stomach.
Esophagus → It is formed from "oiso" (meaning to carry) and "phagein" (meaning to eat). The word describes the tube that carries food to the stomach, thus relating to its function in the digestive system.
Think of the esophagus as the tube that 'carries' ('oiso') food to be 'eaten' ('phagein') — that's why it is called the esophagus.
