Food stays in the esophagus temporarily as it is being transported from the mouth to the stomach. The esophagus uses rhythmic muscle contractions, known as peristalsis, to push the food downward. This process ensures that the food reaches the stomach for digestion. However, if the esophagus is not functioning properly, food may get stuck, leading to a condition known as dysphagia. **

If you need to keep food warm for longer periods, consider using a warming tray or slow cooker to maintain the desired temperature. **
