The esophagus, a tube that carries food to the stomach, is constantly being scraped as food travels through it. Why does the esophagus not deteriorate through a person’s lifetime? Cells can anabolize the food prior to entering the esophagus. Cells are constantly dividing and replacing old or damaged cells.
